Speaker 1 (00:01):
Meet Bob. He's a four time tire rotation champion. When
he was a baby, his first words were automatic transmission fluid.
Bob's so cool he has engine coolant running through his veins.
And then there's Kyle, also known as Premium Unleaded. Legend
has it that Kyle can change your oil with his
toes and that he can tell your tires ill pressure
(00:24):
just by how you're walking out. He's Bob, He's Kyle,
and every Saturday morning they morphed together to form the
greatest superhero known to man. Mister Mechanic check engine lights,
don't stand a chance. This is the Mister Mechanic Show
on eleven ten, kfab.
Speaker 2 (00:45):
Great Saturday morning to you. This is a Mister Mechanic Show.
Five five, eight, eleven ten. As the numbers to get in,
Get in early so we can fill up the lines,
get you an answer back to your question. This is
an interactive call in show. We're live today, we're always
most of the time. Time you got the questions, we
got the answers to get you going. So give us
(01:07):
a call and good morning Kyle. Yeah, a little brisk
out this morning, nice windy for you degrees, which makes
it feel like thirty twenty. But you know the other
day when the wind went through, I think whatever leaves
were around are all gone. They're all in candy, they're
(01:27):
all fence. Yeah, they are all the way there, or
they're all the way in Kansas, one of the two strong.
They had some strong winds even north of US North Dakota,
South Dakota. Yeah.
Speaker 3 (01:39):
I saw something about trains getting blown over in the
whole dime.
Speaker 2 (01:42):
Yeah, kind of crazy. Luckily we didn't have much snow
on the ground, otherwise it would have been a blizzard here.
Otherwise you just get poor gas mileage driving down the road,
that's for sure. You know, an interesting article I noticed
that with all this self driving cars AI wherever that's
taken to us, we're gonna have to have instead of
(02:06):
traffic lights, and you're gonna have red, yellow, and green.
Speaker 3 (02:09):
Are we getting a new one?
Speaker 2 (02:10):
We're getting a new one, Okay, we don't doesn't necessarily
have to be any particular color. They're thinking white, but
it can be any other color which is non confusing
to whatever it is you're trying to figure out and do.
But that's what the car is gonna see, whether or
not whether it should go whether it shouldn't go or
(02:33):
you know, things along that line.
Speaker 3 (02:34):
So I think we need to have it look like
like at the drag strip that start tree. Yeah, it
needs to be something like that because I'm okay with that.
I notice, you know, driving around, because you know the
light will turn green, and I always wait, you know,
an extra five or ten seconds for the three people
that are going to run the red light, and then I'll.
Speaker 2 (02:54):
Go in certain in certain intersections in this town, yes,
you may. It's a it's a must to wait the
extra three to four seconds.
Speaker 3 (03:02):
Eftieth and dodge headed south. You want to wait out
in that one.
Speaker 2 (03:05):
You always want to wait on that. You never want
to wait because there's go because there's somebody's going to
zoom through that.
Speaker 3 (03:11):
You're right, So I think we need at least two
more yellows. So we go from green, yellow, yellow, red,
and then probably a second red.
Speaker 2 (03:22):
You know what's on the and the white one can
what's on the weather scale there, like crimson or magenta.
Maybe we should have a magenta there, something that's like.
Speaker 3 (03:32):
Well, I mean we're already true that we should just
do blue, because I mean, let's incorporate the primary colors First.
Speaker 2 (03:37):
That's true, true red way.
Speaker 3 (03:39):
We'll have to we got our yellow, we got our
green reds there.
Speaker 2 (03:43):
I'm sure there's other intersections in town that are that's
the one we're closest to, and that's one that we
notice the words, and it's the one we get to
see the accident that because gosh, there's a lot of accidents.
Speaker 3 (03:55):
There was a head on accident. I've seen that yesterday,
like fifty first. Yeah, it wasn't even a time. Both
these cars had plenty of time to switch lanes or whatever.
This was an accident out of pride.
Speaker 2 (04:06):
I'm not getting out of my lane. No, you get
out of your lane. Boom, Yeah I did.
Speaker 3 (04:10):
Who's in the wrong there?
Speaker 2 (04:13):
Yeah? And it switches at nine o'clock and yeah, I
haven't seen one of those in a long time.
Speaker 3 (04:18):
I've seen some pretty good ones.
Speaker 2 (04:20):
My guess was somebody who's looking down at their phone,
maybe both of them, and look up and go, oh,
you know.
Speaker 3 (04:27):
So with we were talking just briefly about self driving
cars and how they're coming about and everything, and I
mean with I mean there's gonna be glitches in this
already is Yeah, I'm just waiting for the country song
about the guy's truck leaving him running away.
Speaker 2 (04:47):
Hell yeah, why you're a country singer. There's some right
food for thought there. His wife, his dog, his kids,
is now his car. Yeah, it's got somewhere. It's got
to go pick somebody else up. Yeah. The thing I
thought about with this is, are really people younger generation
just falling out of complete love with driving a car? Yes?
(05:08):
I mean it's just it's so interesting.
Speaker 3 (05:10):
That happens, or just a thing of the past. I mean,
and how how can we if you have a car
with a manual choke and a four on the floor.
I mean, that's all the.
Speaker 2 (05:20):
Anti theft you need, right, true, But there's got to
be a different way around doing it other than traffic lights.
And because I think how many traffic lights are in
the United States? Seven billion? So how many of those?
If you change one, you're going to change them all?
I mean, so you suppose what's a traffic signal up there?
(05:44):
Two three thousand dollars. I don't know what one of
those things costs.
Speaker 3 (05:47):
Well, I mean we're not talking about just, you know,
simply replacing a light bulb.
Speaker 2 (05:50):
We got to add a whole new structure, I know.
So there's an add on and in some places are going.
Speaker 3 (05:55):
What are they going to do it? Stop signs?
Speaker 2 (05:58):
I don't know exactly that that's what I mean. It's
just a it's it's just a whole can of worms
that I think it's got to get worked out besides
replacing seven billion traffic stop traffic lights, that's for sure.
All Right, we're gonna head over to Don. Don's got
a nineteen Chevy bolt with no heat. Don, what's going
(06:19):
on today? This is an electric no heat correct.
Speaker 4 (06:22):
That's right, it's a heat element as electric as for
the heat. The next year they went to a heat pump.
But this one shows has a heat element in it
and it blows cold air. But but then if you
got it turned on the heat the gauges show like
the heater is working, it's just not blowing any The
(06:46):
hot air is not coming out.
Speaker 2 (06:49):
So is it Is it blowing but it's not hot
or not blowing at all.
Speaker 4 (06:53):
It's blowing, but it's not hot, it's blowing cold.
Speaker 3 (06:56):
Ere Okay, so we're going to be looking at the
heating element of this view.
Speaker 2 (07:00):
Right, So.
Speaker 3 (07:02):
What the gauge says like, I'm not I'm very out
of touch with this system. I'm just kind of going on.
Speaker 2 (07:10):
There's not enough of them around to really kind of
for us to see them. But it's going to have
to work simply. It's going to have to go from
a switch that that you're turning on your temperatures have
to going to go down through a fuse, through a relay,
through a heating coil to a heating coil. I mean,
it's it's just no different than a fan hanging in
the garage for more or less. So I think I
(07:34):
would have to start at the fuse and then maybe
gently tap on the switch and see if anything comes about.
Speaker 3 (07:41):
Depending on which system they run this heating element off of,
because I'm.
Speaker 4 (07:48):
Probably running sure that computer, doesn't it?
Speaker 3 (07:51):
Well, everything in the car goes through a computer, yeah,
or a module of some sort. But we have to
figure So there's a twelve volte battery in this car,
is that running this heating element or is this running
off the main through an inverter?
Speaker 2 (08:09):
Yep?
Speaker 3 (08:10):
And like I say that, I'm pretty vague on if
it's going through the inverter. I mean, odds are.
Speaker 2 (08:19):
It's not anything you want to mess with, Yeah, it's
it's something you something you want to stay away from
just because it's got high voltage and you need.
Speaker 3 (08:26):
You put a test light in the wrong spot. It's
time to go buy a new testla Yeah, buy a
new arm and probably jumpstart the old ticket as well.
But I mean that would be where I would start.
I want to find out where this thing's power sources.
If it's powered off the twelve vault DC, no problem.
(08:47):
We can probably get underneath the dash. We can find
where this element is. We can test it. If it's
powered off the eight and eighty.
Speaker 2 (08:53):
Volt DC, stay away. Yeah, you want to find I'd
probably do a little bit more in bestation, maybe on
internet and maybe through some some wiring diagrams. And that's
where I would start, because it's it all depends on
how somebody decided to start that off his life. And
like you said, through the heat pump, that's that's a
(09:14):
little different animal because it's the batteries heating up that
coolant and the coolants what's running through it. I hope
that's help don that that kind of answer your question
or help you a little.
Speaker 4 (09:25):
Bit in a direction, and it helps me a little bit. Yeah,
it's okay, thank you very much.
Speaker 2 (09:31):
You bet not a problem. Yeah, it's uh, we can't
say enough that if it's eight hundred and eighty volts
or four forty or whatever it is in there specifically
you want to you want to be very careful.
Speaker 3 (09:43):
And they're pretty easy to figure out. I mean, if
you find this element, there's orange wires going to it,
like an orange wrap around these wires. You stay away
from those.
Speaker 2 (09:54):
Yeah, there's a whole procedure to get into these cars,
and you just kind of want to follow it.
Speaker 3 (09:58):
And that car, I mean, everything's kind of under the
back seat and before we even work on those, you
pull the back seat and there's a big main fuse
for that and then you pop that out of there
and then you can go through. Right, you're diagnostic when
the system isn't live.
Speaker 2 (10:16):
Yeah, it's like working on the houses basi. You want
to shut off the main before you start poking anything else. So,
all right, we're gonna take a quick break on the
Mister Mechanics Show. Five, five, eight to eleven ten is
the numbers to get in. We've got some open lines.
We'll be back in a minute.
Speaker 5 (10:31):
Can't get a ride, can't drive to school? Oh full
same man, You ain't cool down the street on the
cornex door on the figs you've been waiting for. Hello Daddy,
Hello Mom, on your Jelly Cossic. Come, Hello World.
Speaker 1 (10:53):
I'm your wild girl.
Speaker 5 (10:55):
On your Shelly Cottic.
Speaker 2 (10:58):
Come to Chevy Cossick.
Speaker 5 (11:02):
My interior is practical when it comes to safety.
Speaker 2 (11:07):
Man, I wrote the rules.
Speaker 5 (11:09):
I may not be sixty and I'm no fun, but
Hello Daddy, Hello Mom, Manyo Chicchi to Chevy Cossick ca,
Hello World, Annie a wild draw, I'm your chick to
Chevy Cossick cap.
Speaker 2 (11:29):
We're gonna head over to Joel. Joel's got a sixteen
GMC Sierra Joel, what's up today?
Speaker 6 (11:37):
Good morning, guys. Appreciate the show. So I've had I've
been trying to chase them. The cool fans turning on
as I'm driving, and then you know, turning on immediately
the next time the drive and so forth. I replaced
the thermostat, I replaced the temperature center more than once.
(11:58):
Uh big, A little deeper. It talks about the cooling
fan relay, which mind does not have the cooling fan
relay in the shoes box. So what's my next step?
Speaker 3 (12:14):
Okay, so the cooling fan just comes on whenever it
wants or let me make sure I understand this correctly.
Speaker 6 (12:21):
Whoa, yeah, So, so the temperture gage will just be
buried left and I can drive you to work. It'll
start to come up sometimes and then you know, in
my twenty minute commute, it might drop to the left,
you know, buried left, and the cooling fans are on
(12:44):
at full you know, full speed. Okay, get to work,
shut it up, puling front fans run for another five
ten minutes. And unless I disconnect the battery for five
ten minutes and then reconnect it as soon as I
turn it on again at the end of the day,
the cooling fans are instantly running, okay.
Speaker 3 (13:04):
And the temperature gauge does that stay cold or does
it stay hot?
Speaker 6 (13:07):
Like you explained, stays cold very buried left doesn't register.
Speaker 3 (13:13):
Okay. So let's look at this problem. So you say
you put a cender in it. Yes, so we can
assume that that cender is good. So we need to
actually test it now. So what I would do in
this particular scenario, because the sender tells the computer what's happening,
(13:34):
to tell the gauge what to read. So if we
have a wire that's shorted, so these senders work off
five volts and then whatever comes back on the opposite
side of that center is your return. So what we
need to do first. The tool that I would use
would be a scope, but you can do this with
(13:55):
a multimeter. You're gonna want to backprobe this, and I
wouldn't use your multimeter leads to do this backprobe. You
might have to get something a little bit thinner that
you can kind of stick in this connector and just
touch the back of the the spade inside the connector.
(14:18):
You're going to want to make sure that you have
five volts going into this and then on the other
side you're going to see you know, if you see
five vaults on the other side of it, you know
that either your wires are shorted together somewhere inside the
harness or that your sender's open. Now you're going to
(14:39):
want to as it warms up, you know, you're going
to vary voltage on the opposite side of this cender.
You know, from you know, zero volts all the way
up to five would be a full sweep. You're going
to want to test it there first, because that's pretty
easy there in that driver's side cylinder head. Now, if
you don't have five volts there, so you're starting on
(15:00):
your five volt side at say two volts, then we're
going to be looking for a wire that's shorted something
like that. Maybe it's hitting a bracket, you know, the
alternator bracket there. I know was a problem at some point,
but I think that they've kind of done a TSB
and rerouted that. If it's been done on this truck,
(15:21):
and so let's say everything looks good there, then I
would be going back and testing the same thing at
your computer. So that would be where I because we
know you put a center in it and the relay
that controls the fan. I wouldn't really worry too much
about that because we know our fan works. We know
(15:43):
our issue is in the communications system between this center,
the PCM and your instrument cluster. I would doubt it's
going to be an instrument cluster issue, because that doesn't
say yay or nay is to when the fans come
on or what the temperature is. It's getting all that
in fromtion from the PCM. That gauge is just a hey,
I'm telling you to read this, read this cool kind
(16:06):
of thing.
Speaker 2 (16:07):
Is there a check engine light on it all.
Speaker 6 (16:11):
You know, this has happened multiple times. I think one
time I saw checked engine light tom on.
Speaker 2 (16:16):
Okay, but I mean this for a while. Yeah. The
reason I am thing is what is ahead?
Speaker 6 (16:25):
Well. The other thing is, you know sometimes I can
reset it and it could go six months and not happen.
Then when it starts happening again, it might be you know,
every other day, or it might go a week and
then it'll circ it again. That's pretty intermittent.
Speaker 2 (16:42):
Yeah, So the fans doing what it's doing because it's
in protect mode. It thinks it's got a problem and
it's overheating and it's in protect mode. So if there
is a code in the computer that says U thermostat
code or something along that line, it still thinks it
has a problem. That's why I was wondering if if
there's a code in the computer, or maybe not even
(17:02):
with the check engine light on, there might be something
else in there that's not on. So clearing that code
sets everything back to zero and solves your problem. And
that may happen for a while, like you said, and
then every six months it comes out which.
Speaker 3 (17:18):
Thermostat issues happen when the weather changes. We see a
lot crazy amount of them in the spring February, March, April.
We see a lot of them in the fall September, October, November.
Speaker 2 (17:30):
And even though you've put a new one in, it
depends on the quality of what you've put in. If
everybody graduates towards the eight dollars thermostat, sometimes you need
to get a bigger and better one or one that's
just just more expensive. But then I kind of go,
I agree with Kyle, you're kind of going right back
to a communication error. Something is telling this the computer
(17:53):
X and now it's kind of going into why going
in protect mode, and that's why it's doing what it's doing.
Speaker 3 (18:00):
Do you have any kind of a scanner that'll show
you data of this center?
Speaker 6 (18:06):
I believe I do have a code scanner that I
have not pulled out of my toolbox for more than
a day or two.
Speaker 3 (18:12):
Okay, So I mean that's going to be what we do.
I mean, we're going to hook it up. We're going
to see what the engine coolant temperature censers.
Speaker 2 (18:20):
Saying you're going to look at live data is what
we want to know, and we want to see what
it's it's supposed to what the computers telling it to do?
It is it telling it it's two hundred and sixty
degrees instead of what it actually is outside at you know,
at forty and uh that that could be your problem.
And you know you've got to You've got a computer
sensor and you've also got a temperature center in the block.
(18:44):
So you've got two different sensors there, okay.
Speaker 6 (18:48):
Yeah, and I've only been dealing with the tempature center.
Speaker 2 (18:51):
You can take that and you could have the computer
sensor also sits in the coolant passage and that since
so you've got one for the gauge and then you
got one for the the computer. So we need to
make sure we got the right one, okay, and so.
Speaker 7 (19:09):
Yeah, okay, all right, I'll.
Speaker 2 (19:13):
Scratch my head all right, if hopefully that gets you
a head start. If not, give us a call back.
We'll see what we can do some more for you,
all right. Yeah, we appreciate the call. Yeah, that those
can be kind of weird. It is always kind of
in ninety percent of the time, if not more, when
a GM has a fan that's roaring like crazy, it's
(19:34):
related code. Yes, either coolant slow or that thermostat stuck.
Thermostat stuck. Some of the eco texts have an electronic
thermostat heater that goes bad. I mean there's and so
what they're trying to what they're trying to do there
is that the best optimal mileage. And the reason this
is such a deal is that you get the best
(19:55):
mileage when that cards at the operating temperature. And if
fit's off, let's say it's one ninety five and now
the thermostat opens at one hundred and eighty, you'd be
surprised how much fuel you go through. I get LOCKD.
Speaker 3 (20:09):
You're not going to pass any missions test with it.
Speaker 2 (20:11):
No, I surprise how many people say, you know, I'm
not getting that Grady heat and boy my gas mileage
has gone to trash. Okay, well then I just buy
based on those two things. I know that the thermostat's
bad because those go hand in hand ninety five percent
of the time. So yeah, it's kind of interesting to
dig in. All right, we're gonna take a quick break
(20:33):
on the Mister Mechanics show five, five, eight, eleven, tens
and numbers to get in. So give us a call
way back in a minute. You can in service centers
at fiftieth and Dodge eightieth and Dodge and guaranteed breaks
forty ninth Avenue and Dodge where we do breaks right
the first time. Stop in see us. Let's get you
back on the road. We're gonna head over to David.
David's got a comment. David says, no one wants to
(20:54):
drive old cars anymore. Well, Kyle and I do. Yeah,
what do you drive?
Speaker 8 (21:03):
I have a fifty seven Chevy I just happened to
take out today since Saturday.
Speaker 7 (21:08):
Get some fresh gas in it.
Speaker 3 (21:10):
Oh yeah, enjoy it a little bit?
Speaker 2 (21:11):
Yeah, going.
Speaker 8 (21:13):
And you were talking about young kids. They don't even
know how to drive or start an older car anymore.
And I had my car I was sixteen. My dad
helped me get it in eighty four, and back then
it was just the new rage older cars like that.
And mine's pretty high tech considering is I have a
factory power steering, power brakes and the power glide. But
(21:36):
still I think the new kids would struggle. And I
wouldn't even know how to start at my son's twenty one,
and I'd be concerned about having him do it and
without a lesson.
Speaker 3 (21:46):
That's why they're ls swapping all these yeah, to make
it easy.
Speaker 2 (21:49):
And you're right, they're fun kind of seat to the
pants kind of driving. You know, you got to have
all you.
Speaker 3 (21:56):
Are one with the machine.
Speaker 2 (21:57):
Yeah, you got to have two hands and two legs
and two feet in order to be able to move
everything that goes on more pedals. I mean, I see
the other day with the Only Had they're talking about
some electric cars having one pedal, one for the gas
and one for the break. Well, oh yeah, exactly. How
dumb is that? So I like all the modern not
(22:19):
the modern and the old stuff where it's kind of
you can feel the road and you can hear the
noises and yeah, it's kind of it's kind of neat.
Speaker 3 (22:27):
You can fix it.
Speaker 8 (22:30):
You really have to pay attention. I tell people it
doesn't drive like a Subaru, because if you're not paying attention,
you can be in the ditch really quick.
Speaker 2 (22:37):
Oh yeah, can you imagine taking that car? I mean
back in the day, they didn't know any different because
that's what they had. Can you imagine taking that car
now and start driving over the interstate and going to California?
I mean it take a while exactly. And then of
course back then they had all the parts on wherever
it was. To fix it now you would be just
you know, out of luck.
Speaker 3 (22:58):
But yeah, you gotta find the parts, knows what you're
talking about.
Speaker 2 (23:01):
Yeah, and then the roads we're on now are way
better than the dirt roads that they had and with
the bias by tires, I mean they were living by
the seat of their pants. Is kind of where I'm
going with this. Driving that car down the road at
fifty sixty whatever mile an hour and fish tailing all
over the dirt, it was a It was a different
(23:21):
driving experience for sure.
Speaker 8 (23:23):
That was an adventure getting there.
Speaker 2 (23:26):
Yeah. Yeah, and that's a nice car. As cool car
the Try five Chevys.
Speaker 3 (23:30):
Are, they're hard to find an original condition, I mean
congratulating chopping it original. Yeah, I mean anybody can put
an l less engine. I mean, you got five hundred bucks,
you can get an engine. Toss it in there.
Speaker 8 (23:41):
It's only original one.
Speaker 3 (23:43):
Yeah.
Speaker 2 (23:44):
Yeah, Well, there's plenty of those cars out there. In
Gage's back garage, is behind somebody's house. There's more than
what you know. There's always seems like new stuff pops
up all over the place when you go to a
car show. Hey, David, I appreciate the call all right,
thank you, you bet, thanks for listening. We're going to
head over to Adam. Adam's got an O seven ford
(24:05):
f one fifty. Adam, what's up today?
Speaker 8 (24:08):
Hey guys?
Speaker 2 (24:08):
How's it going great?
Speaker 7 (24:11):
Hey?
Speaker 2 (24:11):
So?
Speaker 9 (24:11):
I got an O seven f one fifty with an
AC problem, not blowing cold air. So I tried the
DIY you know, recharge kit you get an auto park store,
and the gauges on that that thing showed high pressure.
I took it to a shop closer to my house.
They said told me the same thing. There's a blockage
somewhere and they didn't know where, but because I have
(24:33):
aftermarket modifications, they didn't want to work on it. So
I was kind of curious, what, well, the main components,
what should I probably look to first?
Speaker 2 (24:43):
What kind of aftermarket modifications do you have to the
air conditioning?
Speaker 9 (24:48):
Well, I got an electric fans, I got an electric
water pump, and then the supercharger.
Speaker 2 (24:53):
Okay, yeah that shouldn't So can you remember or can
you what they told you as far as you got
to plug in the system? So what were the did
they tell you anything on the gauge readings or what
they were or where they weren't?
Speaker 9 (25:09):
No, not really. They just told me it was high
pressure and the fluid or the refrigerant wasn't slowing, so
I had them just drain everything out because my goal was,
or what I intended to do, is just replace the compressor, condenser,
and dryer, and work got busy and I just never
got around.
Speaker 7 (25:26):
To doing that.
Speaker 3 (25:27):
So, well, those are the main components in your system.
So I mean an AC system, I mean we basically
we're just looking at gauge readings. So if something's plugged,
I mean we got a high and a low side.
If there's a blockage in the system, your low side's
going to be clear into a vacuum, and your high
(25:47):
pressure is going to go up until the switch shuts
it off. Four hundred psi or whatever this one's said
at I can't remember off the top of my head.
So we're going to have to art by looking at gauges.
We're gonna have to have this system charged up. We're
gonna have to see what's happening, because high pressure is
(26:08):
one thing that doesn't necessarily mean that there's a blockage.
Correct low side's in a vacuum. Yeah, i'd buy it,
but if your low side staying you know, thirty to
fifty and your high side's buried, I'm gonna look more
towards a fan issue. You know, something either block between
your radiator and condenser not able to cool this charge,
(26:32):
you know, the EVAPP. I probably wouldn't look at that much.
You know, maybe if I have the system apart, I'm
gonna flush it.
Speaker 2 (26:39):
Sure. And if you've got you've got high pressure on
the high side, and you take a water hose, you
and you cool off your condenser and now all your
temperatures are starting to come back down into normal, Well
that tell me you don't have a plug in the system. Yeah,
you got a flow issue. You got a flow issue,
or you can't. You can't cool off the condenser and
it slowly starts to build eat to the point where
(27:02):
Kyle says it shuts off the high pressure switch. Now,
if you do that same thing and you've got high
pressure and you're you're running cold water over the condenser
and it still stays high pressure and it's not cooling
itself off, then I think you've got a plug somewhere.
So there's the fan is what's scaring them.
Speaker 3 (27:24):
And a garden hose will tell you a lot because
if your fan isn't pulling enough cfm, you're not going
to cool that charge.
Speaker 2 (27:32):
So the water cools it off like a fan would,
and that allows it to work properly. And as soon
as you take the water away and things go back
to a problem, then you know that you're not pulling
March and I'll tell you what and you can answer
this question afterwards. But every time that I have seen
somebody put some sort of aftermarket fan on a car,
(27:54):
whether it's a sixty six Chabelle to you know whatever,
all the way up to any kind of new car,
it just never pulls enough air in order to satisfy
the cooling system. And or when you tax the you
turn the air conditioning on, it taxes that cooling system
another fifty percent. So if it works fine normally when
(28:18):
you turn the air conditioning on, it don't. It makes
me think that the aftermarket fan is just not strong
enough for what you're doing. Why did you throw that
fan on.
Speaker 1 (28:29):
It.
Speaker 9 (28:29):
It's to get rid of the parasitic loss of the
fan anyway, of the clutch fan. So yeah, yep, yeah,
the work for years. It's just in the last two
years that finally quit work.
Speaker 2 (28:41):
In okay.
Speaker 9 (28:42):
So I don't feel like it's the issue.
Speaker 3 (28:44):
Okay, and it might not be, but it's just maybe
it is.
Speaker 2 (28:50):
It's just one thing in play. It's just one thing
in play that and sometimes you got to you got
to take a step backwards before you can take a
step forward sometimes. But you know, what we talked about
with the garden hose is the first way to do that,
and the only Kyle is exactly correct. The only thing
you can do is put a set of gauges on
(29:10):
there and look at your low side and high side
and kind of diagnose it from there. There is nothing
from a one can charge that you're going to get
at any parts store. Every one of those I've ever
tried to put on for somebody because they say, hey,
I've got that can. It always reads high. It always
reads high, and you never know how much you're putting
in and did you overfill it, did gender fill it?
(29:32):
What did you do? So Back in the old days
when we were using our twelve and you could put
a little bit in and check it, put a little
bit in and check it, those days are gone.
Speaker 3 (29:42):
You got to be pretty pretty spot on with your numbers.
And you've got to have it in a good vacuum,
because if there's air in the system, you're going to
have issues.
Speaker 2 (29:49):
Yeah, yep, yep agree. So I guess you need somebody
that is not afraid to work on it. Give us
a call next time, Give us a call next summer.
We see we can help you out. All right, Well
you bet appreciate the call. Yeah, it's just it's just
(30:10):
another air conditioning deal.
Speaker 3 (30:12):
Yeah, air conditioning is still a simple system. I mean,
it hasn't really changed much. I mean, aside from the
ev heat pump deals.
Speaker 2 (30:18):
I mean, some people use fans to kind of cool
off the condenser. We have always found that it's just
much simpler to run some cold water over it.
Speaker 3 (30:27):
It works the same.
Speaker 2 (30:28):
Yeah, it works the same. It's quicker. You don't have
to the water. It reacts quicker. The fan that you
stick in front just takes a little longer to do
and the water cools it right down. And because it's
not going to have it if it's either got to
plug or it don't, it's not going to come and go.
So all right, we're gonna take quick breaking the mister
mechanics show. We'll be back in a minute. This last
(30:48):
collar that is called in. We appreciate your call. Is
air conditioning can be it's either one or two things.
Most time with air conditioning, it's either easy or it's complicated.
There's not much in between. Most of the time. It
is with the condensers nowadays. And he's not on a
bad idea of the condenser being bad because the new
(31:13):
style ribbon condensers that you have these have the orifices
inside of these are super small.
Speaker 3 (31:21):
You can't blow air through.
Speaker 2 (31:22):
You can't blow air through. It's it's like a straw.
It's like a collapse straw, and you just you can't
and if it gets any kind of debris in there,
they plug up pretty quickly. But before we just toss
start tossing things in and spending money, you're better off
to kind of diagnose which problem is before you before
your head there.
Speaker 3 (31:42):
But it's kind of fun to look at those, especially
on that truck, cause it be easy. When you open
the hood, your condenser's right there, right a thermoimaging camera.
You can run the AC and see how much of
your condensers actually working.
Speaker 2 (31:56):
Yeah, remember those were one thousands of dollars and now
either you get one of Harbor Freight for two hundred Yeah,
and uh.
Speaker 3 (32:02):
I mean I picked up a pretty good one on
sale four years ago for like three hundred bucks.
Speaker 2 (32:07):
Yeah.
Speaker 3 (32:07):
And it's the size of my cell phone.
Speaker 2 (32:09):
And you can use that for everything, to go out
and find out which windows bad in the house and
in the wintertime and say, okay, that that one's good,
that one's good. Holy moly, look at that. Yeah, and
see how much loss is going out that that bedroom
window and realize that it doesn't seal.
Speaker 3 (32:25):
So walk around the house at night looking for ghosts.
Speaker 2 (32:27):
Right exactly. That's probably the reason you got in the
first place, Kyle, pretty much. Yeah, all right, we're going
over to Mark. Mark's got a twenty twelve Honda Civix.
Got a transmission problem? Mark? What kind of problem is it?
Speaker 3 (32:39):
Yeah?
Speaker 7 (32:40):
Oh, Hi, it's a when you accelerate out from like
a stop sign or something like that. Right after it's
about twenty twenty five miles an hour, it's sort of
a little shimmi shaped to it, and then it, you know,
for about five or ten miles an hour, and then
it continues and then it's fine after that.
Speaker 2 (32:58):
So, okay, is it not a shut? Sounds like a shutter?
Is this a CVT transmission. Yeah it is, yeah, okay.
How many miles are on it?
Speaker 7 (33:08):
Oh, two hundred and twenty five?
Speaker 3 (33:11):
Has it been service regularly?
Speaker 1 (33:14):
Probably not?
Speaker 2 (33:15):
Yeah, okay, So here's your choice. Drive it as it
is and that shimmy is not that big a deal.
Or you service the transmission and that goes away and
you fix the problem. But at two hundred and twenty
eight thousand miles on it, and you haven't serviced it
at all or as much as you know you can
(33:37):
be prepared for. You're putting brand new slippery fluid in there,
and it just going It goes from a shut or
to not working. There's your three choices right there. It's
when you take that old gritty and this goes for
any transmission, and we've talked about it many times. And
you take that old gritty transmission fluid out of there,
(33:59):
that's kind of whole and everything together and that's what's
making it stick. And you put that brand new, slippery,
greasy stuff in there, it doesn't grab it all anymore.
But okay, I and not on CBT transmissions. I've had
shifting problems and hesitation problems and shuddering problems on other
(34:21):
regular Honda Transmissions changed the fluid and went out and
drove it, and it fixed all the problems it did.
Now CBT is a different animal completely. That's that's not
the same thing as what I'm talking about. But those
are the three things that you got going. It's either
gonna live with it, change it, but be prepared what's
(34:44):
going to happen if you change it.
Speaker 3 (34:48):
And if you do decide to change this yourself, don't
do it in the garage. Back it outside.
Speaker 2 (34:53):
It smells, it sticks.
Speaker 3 (34:55):
You will not get the smell out of your garage.
Speaker 2 (34:58):
Your life's going to be mad. You maybe leave it well,
maybe if that's what you want, Leave the door open
a little bit, turn a fan on, maybe push it
towards the house. She'll be gone for she'ld be gone
for four days for sure. But yeah, I did take
do it outside. And you might want to price that job.
(35:19):
I would if it was if it was me and
your shoes, I would price that job of what a
cost to do that. That way you kind of know
where you're heading. Maybe that helps you make your decision. Okay, thanks, Mark,
appreciate the call. All right, we got another call. No,
we'll do that off there yeah.
Speaker 3 (35:39):
Interesting transmissions are getting complicated.
Speaker 2 (35:42):
They are, they are, and they not that.
Speaker 3 (35:44):
They've ever been easy as far as automatic transmissions.
Speaker 2 (35:48):
So theo CBTs run like if anybody knows well. They
run on a metal belt.
Meet Bob. He's a four time tire rotation champion. When
he was a baby, his first words were automatic transmission fluid.
Bob's so cool he has engine coolant running through his veins.
And then there's Kyle, also known as Premium Unleaded. Legend
has it that Kyle can change your oil with his
toes and that he can tell your tires ill pressure
(00:24):
just by how you're walking out. He's Bob, He's Kyle,
and every Saturday morning they morphed together to form the
greatest superhero known to man. Mister Mechanic check engine lights,
don't stand a chance. This is the Mister Mechanic Show
on eleven ten, kfab.
Speaker 2 (00:45):
Great Saturday morning to you. This is a Mister Mechanic Show.
Five five, eight, eleven ten. As the numbers to get in,
Get in early so we can fill up the lines,
get you an answer back to your question. This is
an interactive call in show. We're live today, we're always
most of the time. Time you got the questions, we
got the answers to get you going. So give us
(01:07):
a call and good morning Kyle. Yeah, a little brisk
out this morning, nice windy for you degrees, which makes
it feel like thirty twenty. But you know the other
day when the wind went through, I think whatever leaves
were around are all gone. They're all in candy, they're
(01:27):
all fence. Yeah, they are all the way there, or
they're all the way in Kansas, one of the two strong.
They had some strong winds even north of US North Dakota,
South Dakota. Yeah.
Speaker 3 (01:39):
I saw something about trains getting blown over in the
whole dime.
Speaker 2 (01:42):
Yeah, kind of crazy. Luckily we didn't have much snow
on the ground, otherwise it would have been a blizzard here.
Otherwise you just get poor gas mileage driving down the road,
that's for sure. You know, an interesting article I noticed
that with all this self driving cars AI wherever that's
taken to us, we're gonna have to have instead of
(02:06):
traffic lights, and you're gonna have red, yellow, and green.
Speaker 3 (02:09):
Are we getting a new one?
Speaker 2 (02:10):
We're getting a new one, Okay, we don't doesn't necessarily
have to be any particular color. They're thinking white, but
it can be any other color which is non confusing
to whatever it is you're trying to figure out and do.
But that's what the car is gonna see, whether or
not whether it should go whether it shouldn't go or
(02:33):
you know, things along that line.
Speaker 3 (02:34):
So I think we need to have it look like
like at the drag strip that start tree. Yeah, it
needs to be something like that because I'm okay with that.
I notice, you know, driving around, because you know the
light will turn green, and I always wait, you know,
an extra five or ten seconds for the three people
that are going to run the red light, and then I'll.
Speaker 2 (02:54):
Go in certain in certain intersections in this town, yes,
you may. It's a it's a must to wait the
extra three to four seconds.
Speaker 3 (03:02):
Eftieth and dodge headed south. You want to wait out
in that one.
Speaker 2 (03:05):
You always want to wait on that. You never want
to wait because there's go because there's somebody's going to
zoom through that.
Speaker 3 (03:11):
You're right, So I think we need at least two
more yellows. So we go from green, yellow, yellow, red,
and then probably a second red.
Speaker 2 (03:22):
You know what's on the and the white one can
what's on the weather scale there, like crimson or magenta.
Maybe we should have a magenta there, something that's like.
Speaker 3 (03:32):
Well, I mean we're already true that we should just
do blue, because I mean, let's incorporate the primary colors First.
Speaker 2 (03:37):
That's true, true red way.
Speaker 3 (03:39):
We'll have to we got our yellow, we got our
green reds there.
Speaker 2 (03:43):
I'm sure there's other intersections in town that are that's
the one we're closest to, and that's one that we
notice the words, and it's the one we get to
see the accident that because gosh, there's a lot of accidents.
Speaker 3 (03:55):
There was a head on accident. I've seen that yesterday,
like fifty first. Yeah, it wasn't even a time. Both
these cars had plenty of time to switch lanes or whatever.
This was an accident out of pride.
Speaker 2 (04:06):
I'm not getting out of my lane. No, you get
out of your lane. Boom, Yeah I did.
Speaker 3 (04:10):
Who's in the wrong there?
Speaker 2 (04:13):
Yeah? And it switches at nine o'clock and yeah, I
haven't seen one of those in a long time.
Speaker 3 (04:18):
I've seen some pretty good ones.
Speaker 2 (04:20):
My guess was somebody who's looking down at their phone,
maybe both of them, and look up and go, oh,
you know.
Speaker 3 (04:27):
So with we were talking just briefly about self driving
cars and how they're coming about and everything, and I
mean with I mean there's gonna be glitches in this
already is Yeah, I'm just waiting for the country song
about the guy's truck leaving him running away.
Speaker 2 (04:47):
Hell yeah, why you're a country singer. There's some right
food for thought there. His wife, his dog, his kids,
is now his car. Yeah, it's got somewhere. It's got
to go pick somebody else up. Yeah. The thing I
thought about with this is, are really people younger generation
just falling out of complete love with driving a car? Yes?
(05:08):
I mean it's just it's so interesting.
Speaker 3 (05:10):
That happens, or just a thing of the past. I mean,
and how how can we if you have a car
with a manual choke and a four on the floor.
I mean, that's all the.
Speaker 2 (05:20):
Anti theft you need, right, true, But there's got to
be a different way around doing it other than traffic lights.
And because I think how many traffic lights are in
the United States? Seven billion? So how many of those?
If you change one, you're going to change them all?
I mean, so you suppose what's a traffic signal up there?
(05:44):
Two three thousand dollars. I don't know what one of
those things costs.
Speaker 3 (05:47):
Well, I mean we're not talking about just, you know,
simply replacing a light bulb.
Speaker 2 (05:50):
We got to add a whole new structure, I know.
So there's an add on and in some places are going.
Speaker 3 (05:55):
What are they going to do it? Stop signs?
Speaker 2 (05:58):
I don't know exactly that that's what I mean. It's
just a it's it's just a whole can of worms
that I think it's got to get worked out besides
replacing seven billion traffic stop traffic lights, that's for sure.
All Right, we're gonna head over to Don. Don's got
a nineteen Chevy bolt with no heat. Don, what's going
(06:19):
on today? This is an electric no heat correct.
Speaker 4 (06:22):
That's right, it's a heat element as electric as for
the heat. The next year they went to a heat pump.
But this one shows has a heat element in it
and it blows cold air. But but then if you
got it turned on the heat the gauges show like
the heater is working, it's just not blowing any The
(06:46):
hot air is not coming out.
Speaker 2 (06:49):
So is it Is it blowing but it's not hot
or not blowing at all.
Speaker 4 (06:53):
It's blowing, but it's not hot, it's blowing cold.
Speaker 3 (06:56):
Ere Okay, so we're going to be looking at the
heating element of this view.
Speaker 2 (07:00):
Right, So.
Speaker 3 (07:02):
What the gauge says like, I'm not I'm very out
of touch with this system. I'm just kind of going on.
Speaker 2 (07:10):
There's not enough of them around to really kind of
for us to see them. But it's going to have
to work simply. It's going to have to go from
a switch that that you're turning on your temperatures have
to going to go down through a fuse, through a relay,
through a heating coil to a heating coil. I mean,
it's it's just no different than a fan hanging in
the garage for more or less. So I think I
(07:34):
would have to start at the fuse and then maybe
gently tap on the switch and see if anything comes about.
Speaker 3 (07:41):
Depending on which system they run this heating element off of,
because I'm.
Speaker 4 (07:48):
Probably running sure that computer, doesn't it?
Speaker 3 (07:51):
Well, everything in the car goes through a computer, yeah,
or a module of some sort. But we have to
figure So there's a twelve volte battery in this car,
is that running this heating element or is this running
off the main through an inverter?
Speaker 2 (08:09):
Yep?
Speaker 3 (08:10):
And like I say that, I'm pretty vague on if
it's going through the inverter. I mean, odds are.
Speaker 2 (08:19):
It's not anything you want to mess with, Yeah, it's
it's something you something you want to stay away from
just because it's got high voltage and you need.
Speaker 3 (08:26):
You put a test light in the wrong spot. It's
time to go buy a new testla Yeah, buy a
new arm and probably jumpstart the old ticket as well.
But I mean that would be where I would start.
I want to find out where this thing's power sources.
If it's powered off the twelve vault DC, no problem.
(08:47):
We can probably get underneath the dash. We can find
where this element is. We can test it. If it's
powered off the eight and eighty.
Speaker 2 (08:53):
Volt DC, stay away. Yeah, you want to find I'd
probably do a little bit more in bestation, maybe on
internet and maybe through some some wiring diagrams. And that's
where I would start, because it's it all depends on
how somebody decided to start that off his life. And
like you said, through the heat pump, that's that's a
(09:14):
little different animal because it's the batteries heating up that
coolant and the coolants what's running through it. I hope
that's help don that that kind of answer your question
or help you a little.
Speaker 4 (09:25):
Bit in a direction, and it helps me a little bit. Yeah,
it's okay, thank you very much.
Speaker 2 (09:31):
You bet not a problem. Yeah, it's uh, we can't
say enough that if it's eight hundred and eighty volts
or four forty or whatever it is in there specifically
you want to you want to be very careful.
Speaker 3 (09:43):
And they're pretty easy to figure out. I mean, if
you find this element, there's orange wires going to it,
like an orange wrap around these wires. You stay away
from those.
Speaker 2 (09:54):
Yeah, there's a whole procedure to get into these cars,
and you just kind of want to follow it.
Speaker 3 (09:58):
And that car, I mean, everything's kind of under the
back seat and before we even work on those, you
pull the back seat and there's a big main fuse
for that and then you pop that out of there
and then you can go through. Right, you're diagnostic when
the system isn't live.
Speaker 2 (10:16):
Yeah, it's like working on the houses basi. You want
to shut off the main before you start poking anything else. So,
all right, we're gonna take a quick break on the
Mister Mechanics Show. Five, five, eight to eleven ten is
the numbers to get in. We've got some open lines.
We'll be back in a minute.
Speaker 5 (10:31):
Can't get a ride, can't drive to school? Oh full
same man, You ain't cool down the street on the
cornex door on the figs you've been waiting for. Hello Daddy,
Hello Mom, on your Jelly Cossic. Come, Hello World.
Speaker 1 (10:53):
I'm your wild girl.
Speaker 5 (10:55):
On your Shelly Cottic.
Speaker 2 (10:58):
Come to Chevy Cossick.
Speaker 5 (11:02):
My interior is practical when it comes to safety.
Speaker 2 (11:07):
Man, I wrote the rules.
Speaker 5 (11:09):
I may not be sixty and I'm no fun, but
Hello Daddy, Hello Mom, Manyo Chicchi to Chevy Cossick ca,
Hello World, Annie a wild draw, I'm your chick to
Chevy Cossick cap.
Speaker 2 (11:29):
We're gonna head over to Joel. Joel's got a sixteen
GMC Sierra Joel, what's up today?
Speaker 6 (11:37):
Good morning, guys. Appreciate the show. So I've had I've
been trying to chase them. The cool fans turning on
as I'm driving, and then you know, turning on immediately
the next time the drive and so forth. I replaced
the thermostat, I replaced the temperature center more than once.
(11:58):
Uh big, A little deeper. It talks about the cooling
fan relay, which mind does not have the cooling fan
relay in the shoes box. So what's my next step?
Speaker 3 (12:14):
Okay, so the cooling fan just comes on whenever it
wants or let me make sure I understand this correctly.
Speaker 6 (12:21):
Whoa, yeah, So, so the temperture gage will just be
buried left and I can drive you to work. It'll
start to come up sometimes and then you know, in
my twenty minute commute, it might drop to the left,
you know, buried left, and the cooling fans are on
(12:44):
at full you know, full speed. Okay, get to work,
shut it up, puling front fans run for another five
ten minutes. And unless I disconnect the battery for five
ten minutes and then reconnect it as soon as I
turn it on again at the end of the day,
the cooling fans are instantly running, okay.
Speaker 3 (13:04):
And the temperature gauge does that stay cold or does
it stay hot?
Speaker 6 (13:07):
Like you explained, stays cold very buried left doesn't register.
Speaker 3 (13:13):
Okay. So let's look at this problem. So you say
you put a cender in it. Yes, so we can
assume that that cender is good. So we need to
actually test it now. So what I would do in
this particular scenario, because the sender tells the computer what's happening,
(13:34):
to tell the gauge what to read. So if we
have a wire that's shorted, so these senders work off
five volts and then whatever comes back on the opposite
side of that center is your return. So what we
need to do first. The tool that I would use
would be a scope, but you can do this with
(13:55):
a multimeter. You're gonna want to backprobe this, and I
wouldn't use your multimeter leads to do this backprobe. You
might have to get something a little bit thinner that
you can kind of stick in this connector and just
touch the back of the the spade inside the connector.
(14:18):
You're going to want to make sure that you have
five volts going into this and then on the other
side you're going to see you know, if you see
five vaults on the other side of it, you know
that either your wires are shorted together somewhere inside the
harness or that your sender's open. Now you're going to
(14:39):
want to as it warms up, you know, you're going
to vary voltage on the opposite side of this cender.
You know, from you know, zero volts all the way
up to five would be a full sweep. You're going
to want to test it there first, because that's pretty
easy there in that driver's side cylinder head. Now, if
you don't have five volts there, so you're starting on
(15:00):
your five volt side at say two volts, then we're
going to be looking for a wire that's shorted something
like that. Maybe it's hitting a bracket, you know, the
alternator bracket there. I know was a problem at some point,
but I think that they've kind of done a TSB
and rerouted that. If it's been done on this truck,
(15:21):
and so let's say everything looks good there, then I
would be going back and testing the same thing at
your computer. So that would be where I because we
know you put a center in it and the relay
that controls the fan. I wouldn't really worry too much
about that because we know our fan works. We know
(15:43):
our issue is in the communications system between this center,
the PCM and your instrument cluster. I would doubt it's
going to be an instrument cluster issue, because that doesn't
say yay or nay is to when the fans come
on or what the temperature is. It's getting all that
in fromtion from the PCM. That gauge is just a hey,
I'm telling you to read this, read this cool kind
(16:06):
of thing.
Speaker 2 (16:07):
Is there a check engine light on it all.
Speaker 6 (16:11):
You know, this has happened multiple times. I think one
time I saw checked engine light tom on.
Speaker 2 (16:16):
Okay, but I mean this for a while. Yeah. The
reason I am thing is what is ahead?
Speaker 6 (16:25):
Well. The other thing is, you know sometimes I can
reset it and it could go six months and not happen.
Then when it starts happening again, it might be you know,
every other day, or it might go a week and
then it'll circ it again. That's pretty intermittent.
Speaker 2 (16:42):
Yeah, So the fans doing what it's doing because it's
in protect mode. It thinks it's got a problem and
it's overheating and it's in protect mode. So if there
is a code in the computer that says U thermostat
code or something along that line, it still thinks it
has a problem. That's why I was wondering if if
there's a code in the computer, or maybe not even
(17:02):
with the check engine light on, there might be something
else in there that's not on. So clearing that code
sets everything back to zero and solves your problem. And
that may happen for a while, like you said, and
then every six months it comes out which.
Speaker 3 (17:18):
Thermostat issues happen when the weather changes. We see a
lot crazy amount of them in the spring February, March, April.
We see a lot of them in the fall September, October, November.
Speaker 2 (17:30):
And even though you've put a new one in, it
depends on the quality of what you've put in. If
everybody graduates towards the eight dollars thermostat, sometimes you need
to get a bigger and better one or one that's
just just more expensive. But then I kind of go,
I agree with Kyle, you're kind of going right back
to a communication error. Something is telling this the computer
(17:53):
X and now it's kind of going into why going
in protect mode, and that's why it's doing what it's doing.
Speaker 3 (18:00):
Do you have any kind of a scanner that'll show
you data of this center?
Speaker 6 (18:06):
I believe I do have a code scanner that I
have not pulled out of my toolbox for more than
a day or two.
Speaker 3 (18:12):
Okay, So I mean that's going to be what we do.
I mean, we're going to hook it up. We're going
to see what the engine coolant temperature censers.
Speaker 2 (18:20):
Saying you're going to look at live data is what
we want to know, and we want to see what
it's it's supposed to what the computers telling it to do?
It is it telling it it's two hundred and sixty
degrees instead of what it actually is outside at you know,
at forty and uh that that could be your problem.
And you know you've got to You've got a computer
sensor and you've also got a temperature center in the block.
(18:44):
So you've got two different sensors there, okay.
Speaker 6 (18:48):
Yeah, and I've only been dealing with the tempature center.
Speaker 2 (18:51):
You can take that and you could have the computer
sensor also sits in the coolant passage and that since
so you've got one for the gauge and then you
got one for the the computer. So we need to
make sure we got the right one, okay, and so.
Speaker 7 (19:09):
Yeah, okay, all right, I'll.
Speaker 2 (19:13):
Scratch my head all right, if hopefully that gets you
a head start. If not, give us a call back.
We'll see what we can do some more for you,
all right. Yeah, we appreciate the call. Yeah, that those
can be kind of weird. It is always kind of
in ninety percent of the time, if not more, when
a GM has a fan that's roaring like crazy, it's
(19:34):
related code. Yes, either coolant slow or that thermostat stuck.
Thermostat stuck. Some of the eco texts have an electronic
thermostat heater that goes bad. I mean there's and so
what they're trying to what they're trying to do there
is that the best optimal mileage. And the reason this
is such a deal is that you get the best
(19:55):
mileage when that cards at the operating temperature. And if
fit's off, let's say it's one ninety five and now
the thermostat opens at one hundred and eighty, you'd be
surprised how much fuel you go through. I get LOCKD.
Speaker 3 (20:09):
You're not going to pass any missions test with it.
Speaker 2 (20:11):
No, I surprise how many people say, you know, I'm
not getting that Grady heat and boy my gas mileage
has gone to trash. Okay, well then I just buy
based on those two things. I know that the thermostat's
bad because those go hand in hand ninety five percent
of the time. So yeah, it's kind of interesting to
dig in. All right, we're gonna take a quick break
(20:33):
on the Mister Mechanics show five, five, eight, eleven, tens
and numbers to get in. So give us a call
way back in a minute. You can in service centers
at fiftieth and Dodge eightieth and Dodge and guaranteed breaks
forty ninth Avenue and Dodge where we do breaks right
the first time. Stop in see us. Let's get you
back on the road. We're gonna head over to David.
David's got a comment. David says, no one wants to
(20:54):
drive old cars anymore. Well, Kyle and I do. Yeah,
what do you drive?
Speaker 8 (21:03):
I have a fifty seven Chevy I just happened to
take out today since Saturday.
Speaker 7 (21:08):
Get some fresh gas in it.
Speaker 3 (21:10):
Oh yeah, enjoy it a little bit?
Speaker 2 (21:11):
Yeah, going.
Speaker 8 (21:13):
And you were talking about young kids. They don't even
know how to drive or start an older car anymore.
And I had my car I was sixteen. My dad
helped me get it in eighty four, and back then
it was just the new rage older cars like that.
And mine's pretty high tech considering is I have a
factory power steering, power brakes and the power glide. But
(21:36):
still I think the new kids would struggle. And I
wouldn't even know how to start at my son's twenty one,
and I'd be concerned about having him do it and
without a lesson.
Speaker 3 (21:46):
That's why they're ls swapping all these yeah, to make
it easy.
Speaker 2 (21:49):
And you're right, they're fun kind of seat to the
pants kind of driving. You know, you got to have
all you.
Speaker 3 (21:56):
Are one with the machine.
Speaker 2 (21:57):
Yeah, you got to have two hands and two legs
and two feet in order to be able to move
everything that goes on more pedals. I mean, I see
the other day with the Only Had they're talking about
some electric cars having one pedal, one for the gas
and one for the break. Well, oh yeah, exactly. How
dumb is that? So I like all the modern not
(22:19):
the modern and the old stuff where it's kind of
you can feel the road and you can hear the
noises and yeah, it's kind of it's kind of neat.
Speaker 3 (22:27):
You can fix it.
Speaker 8 (22:30):
You really have to pay attention. I tell people it
doesn't drive like a Subaru, because if you're not paying attention,
you can be in the ditch really quick.
Speaker 2 (22:37):
Oh yeah, can you imagine taking that car? I mean
back in the day, they didn't know any different because
that's what they had. Can you imagine taking that car
now and start driving over the interstate and going to California?
I mean it take a while exactly. And then of
course back then they had all the parts on wherever
it was. To fix it now you would be just
you know, out of luck.
Speaker 3 (22:58):
But yeah, you gotta find the parts, knows what you're
talking about.
Speaker 2 (23:01):
Yeah, and then the roads we're on now are way
better than the dirt roads that they had and with
the bias by tires, I mean they were living by
the seat of their pants. Is kind of where I'm
going with this. Driving that car down the road at
fifty sixty whatever mile an hour and fish tailing all
over the dirt, it was a It was a different
(23:21):
driving experience for sure.
Speaker 8 (23:23):
That was an adventure getting there.
Speaker 2 (23:26):
Yeah. Yeah, and that's a nice car. As cool car
the Try five Chevys.
Speaker 3 (23:30):
Are, they're hard to find an original condition, I mean
congratulating chopping it original. Yeah, I mean anybody can put
an l less engine. I mean, you got five hundred bucks,
you can get an engine. Toss it in there.
Speaker 8 (23:41):
It's only original one.
Speaker 3 (23:43):
Yeah.
Speaker 2 (23:44):
Yeah, Well, there's plenty of those cars out there. In
Gage's back garage, is behind somebody's house. There's more than
what you know. There's always seems like new stuff pops
up all over the place when you go to a
car show. Hey, David, I appreciate the call all right,
thank you, you bet, thanks for listening. We're going to
head over to Adam. Adam's got an O seven ford
(24:05):
f one fifty. Adam, what's up today?
Speaker 8 (24:08):
Hey guys?
Speaker 2 (24:08):
How's it going great?
Speaker 7 (24:11):
Hey?
Speaker 2 (24:11):
So?
Speaker 9 (24:11):
I got an O seven f one fifty with an
AC problem, not blowing cold air. So I tried the
DIY you know, recharge kit you get an auto park store,
and the gauges on that that thing showed high pressure.
I took it to a shop closer to my house.
They said told me the same thing. There's a blockage
somewhere and they didn't know where, but because I have
(24:33):
aftermarket modifications, they didn't want to work on it. So
I was kind of curious, what, well, the main components,
what should I probably look to first?
Speaker 2 (24:43):
What kind of aftermarket modifications do you have to the
air conditioning?
Speaker 9 (24:48):
Well, I got an electric fans, I got an electric
water pump, and then the supercharger.
Speaker 2 (24:53):
Okay, yeah that shouldn't So can you remember or can
you what they told you as far as you got
to plug in the system? So what were the did
they tell you anything on the gauge readings or what
they were or where they weren't?
Speaker 9 (25:09):
No, not really. They just told me it was high
pressure and the fluid or the refrigerant wasn't slowing, so
I had them just drain everything out because my goal was,
or what I intended to do, is just replace the compressor, condenser,
and dryer, and work got busy and I just never
got around.
Speaker 7 (25:26):
To doing that.
Speaker 3 (25:27):
So, well, those are the main components in your system.
So I mean an AC system, I mean we basically
we're just looking at gauge readings. So if something's plugged,
I mean we got a high and a low side.
If there's a blockage in the system, your low side's
going to be clear into a vacuum, and your high
(25:47):
pressure is going to go up until the switch shuts
it off. Four hundred psi or whatever this one's said
at I can't remember off the top of my head.
So we're going to have to art by looking at gauges.
We're gonna have to have this system charged up. We're
gonna have to see what's happening, because high pressure is
(26:08):
one thing that doesn't necessarily mean that there's a blockage.
Correct low side's in a vacuum. Yeah, i'd buy it,
but if your low side staying you know, thirty to
fifty and your high side's buried, I'm gonna look more
towards a fan issue. You know, something either block between
your radiator and condenser not able to cool this charge,
(26:32):
you know, the EVAPP. I probably wouldn't look at that much.
You know, maybe if I have the system apart, I'm
gonna flush it.
Speaker 2 (26:39):
Sure. And if you've got you've got high pressure on
the high side, and you take a water hose, you
and you cool off your condenser and now all your
temperatures are starting to come back down into normal, Well
that tell me you don't have a plug in the system. Yeah,
you got a flow issue. You got a flow issue,
or you can't. You can't cool off the condenser and
it slowly starts to build eat to the point where
(27:02):
Kyle says it shuts off the high pressure switch. Now,
if you do that same thing and you've got high
pressure and you're you're running cold water over the condenser
and it still stays high pressure and it's not cooling
itself off, then I think you've got a plug somewhere.
So there's the fan is what's scaring them.
Speaker 3 (27:24):
And a garden hose will tell you a lot because
if your fan isn't pulling enough cfm, you're not going
to cool that charge.
Speaker 2 (27:32):
So the water cools it off like a fan would,
and that allows it to work properly. And as soon
as you take the water away and things go back
to a problem, then you know that you're not pulling
March and I'll tell you what and you can answer
this question afterwards. But every time that I have seen
somebody put some sort of aftermarket fan on a car,
(27:54):
whether it's a sixty six Chabelle to you know whatever,
all the way up to any kind of new car,
it just never pulls enough air in order to satisfy
the cooling system. And or when you tax the you
turn the air conditioning on, it taxes that cooling system
another fifty percent. So if it works fine normally when
(28:18):
you turn the air conditioning on, it don't. It makes
me think that the aftermarket fan is just not strong
enough for what you're doing. Why did you throw that
fan on.
Speaker 1 (28:29):
It.
Speaker 9 (28:29):
It's to get rid of the parasitic loss of the
fan anyway, of the clutch fan. So yeah, yep, yeah,
the work for years. It's just in the last two
years that finally quit work.
Speaker 2 (28:41):
In okay.
Speaker 9 (28:42):
So I don't feel like it's the issue.
Speaker 3 (28:44):
Okay, and it might not be, but it's just maybe
it is.
Speaker 2 (28:50):
It's just one thing in play. It's just one thing
in play that and sometimes you got to you got
to take a step backwards before you can take a
step forward sometimes. But you know, what we talked about
with the garden hose is the first way to do that,
and the only Kyle is exactly correct. The only thing
you can do is put a set of gauges on
(29:10):
there and look at your low side and high side
and kind of diagnose it from there. There is nothing
from a one can charge that you're going to get
at any parts store. Every one of those I've ever
tried to put on for somebody because they say, hey,
I've got that can. It always reads high. It always
reads high, and you never know how much you're putting
in and did you overfill it, did gender fill it?
(29:32):
What did you do? So Back in the old days
when we were using our twelve and you could put
a little bit in and check it, put a little
bit in and check it, those days are gone.
Speaker 3 (29:42):
You got to be pretty pretty spot on with your numbers.
And you've got to have it in a good vacuum,
because if there's air in the system, you're going to
have issues.
Speaker 2 (29:49):
Yeah, yep, yep agree. So I guess you need somebody
that is not afraid to work on it. Give us
a call next time, Give us a call next summer.
We see we can help you out. All right, Well
you bet appreciate the call. Yeah, it's just it's just
(30:10):
another air conditioning deal.
Speaker 3 (30:12):
Yeah, air conditioning is still a simple system. I mean,
it hasn't really changed much. I mean, aside from the
ev heat pump deals.
Speaker 2 (30:18):
I mean, some people use fans to kind of cool
off the condenser. We have always found that it's just
much simpler to run some cold water over it.
Speaker 3 (30:27):
It works the same.
Speaker 2 (30:28):
Yeah, it works the same. It's quicker. You don't have
to the water. It reacts quicker. The fan that you
stick in front just takes a little longer to do
and the water cools it right down. And because it's
not going to have it if it's either got to
plug or it don't, it's not going to come and go.
So all right, we're gonna take quick breaking the mister
mechanics show. We'll be back in a minute. This last
(30:48):
collar that is called in. We appreciate your call. Is
air conditioning can be it's either one or two things.
Most time with air conditioning, it's either easy or it's complicated.
There's not much in between. Most of the time. It
is with the condensers nowadays. And he's not on a
bad idea of the condenser being bad because the new
(31:13):
style ribbon condensers that you have these have the orifices
inside of these are super small.
Speaker 3 (31:21):
You can't blow air through.
Speaker 2 (31:22):
You can't blow air through. It's it's like a straw.
It's like a collapse straw, and you just you can't
and if it gets any kind of debris in there,
they plug up pretty quickly. But before we just toss
start tossing things in and spending money, you're better off
to kind of diagnose which problem is before you before
your head there.
Speaker 3 (31:42):
But it's kind of fun to look at those, especially
on that truck, cause it be easy. When you open
the hood, your condenser's right there, right a thermoimaging camera.
You can run the AC and see how much of
your condensers actually working.
Speaker 2 (31:56):
Yeah, remember those were one thousands of dollars and now
either you get one of Harbor Freight for two hundred Yeah,
and uh.
Speaker 3 (32:02):
I mean I picked up a pretty good one on
sale four years ago for like three hundred bucks.
Speaker 2 (32:07):
Yeah.
Speaker 3 (32:07):
And it's the size of my cell phone.
Speaker 2 (32:09):
And you can use that for everything, to go out
and find out which windows bad in the house and
in the wintertime and say, okay, that that one's good,
that one's good. Holy moly, look at that. Yeah, and
see how much loss is going out that that bedroom
window and realize that it doesn't seal.
Speaker 3 (32:25):
So walk around the house at night looking for ghosts.
Speaker 2 (32:27):
Right exactly. That's probably the reason you got in the
first place, Kyle, pretty much. Yeah, all right, we're going
over to Mark. Mark's got a twenty twelve Honda Civix.
Got a transmission problem? Mark? What kind of problem is it?
Speaker 3 (32:39):
Yeah?
Speaker 7 (32:40):
Oh, Hi, it's a when you accelerate out from like
a stop sign or something like that. Right after it's
about twenty twenty five miles an hour, it's sort of
a little shimmi shaped to it, and then it, you know,
for about five or ten miles an hour, and then
it continues and then it's fine after that.
Speaker 2 (32:58):
So, okay, is it not a shut? Sounds like a shutter?
Is this a CVT transmission. Yeah it is, yeah, okay.
How many miles are on it?
Speaker 7 (33:08):
Oh, two hundred and twenty five?
Speaker 3 (33:11):
Has it been service regularly?
Speaker 1 (33:14):
Probably not?
Speaker 2 (33:15):
Yeah, okay, So here's your choice. Drive it as it
is and that shimmy is not that big a deal.
Or you service the transmission and that goes away and
you fix the problem. But at two hundred and twenty
eight thousand miles on it, and you haven't serviced it
at all or as much as you know you can
(33:37):
be prepared for. You're putting brand new slippery fluid in there,
and it just going It goes from a shut or
to not working. There's your three choices right there. It's
when you take that old gritty and this goes for
any transmission, and we've talked about it many times. And
you take that old gritty transmission fluid out of there,
(33:59):
that's kind of whole and everything together and that's what's
making it stick. And you put that brand new, slippery,
greasy stuff in there, it doesn't grab it all anymore.
But okay, I and not on CBT transmissions. I've had
shifting problems and hesitation problems and shuddering problems on other
(34:21):
regular Honda Transmissions changed the fluid and went out and
drove it, and it fixed all the problems it did.
Now CBT is a different animal completely. That's that's not
the same thing as what I'm talking about. But those
are the three things that you got going. It's either
gonna live with it, change it, but be prepared what's
(34:44):
going to happen if you change it.
Speaker 3 (34:48):
And if you do decide to change this yourself, don't
do it in the garage. Back it outside.
Speaker 2 (34:53):
It smells, it sticks.
Speaker 3 (34:55):
You will not get the smell out of your garage.
Speaker 2 (34:58):
Your life's going to be mad. You maybe leave it well,
maybe if that's what you want, Leave the door open
a little bit, turn a fan on, maybe push it
towards the house. She'll be gone for she'ld be gone
for four days for sure. But yeah, I did take
do it outside. And you might want to price that job.
(35:19):
I would if it was if it was me and
your shoes, I would price that job of what a
cost to do that. That way you kind of know
where you're heading. Maybe that helps you make your decision. Okay, thanks, Mark,
appreciate the call. All right, we got another call. No,
we'll do that off there yeah.
Speaker 3 (35:39):
Interesting transmissions are getting complicated.
Speaker 2 (35:42):
They are, they are, and they not that.
Speaker 3 (35:44):
They've ever been easy as far as automatic transmissions.
Speaker 2 (35:48):
So theo CBTs run like if anybody knows well. They
run on a metal belt.

The Burden
The Burden is a documentary series that takes listeners into the hidden places where justice is done (and undone). It dives deep into the lives of heroes and villains. And it focuses a spotlight on those who triumph even when the odds are against them. Season 5 - The Burden: Death & Deceit in Alliance On April Fools Day 1999, 26-year-old Yvonne Layne was found murdered in her Alliance, Ohio home. David Thorne, her ex-boyfriend and father of one of her children, was instantly a suspect. Another young man admitted to the murder, and David breathed a sigh of relief, until the confessed murderer fingered David; “He paid me to do it.” David was sentenced to life without parole. Two decades later, Pulitzer winner and podcast host, Maggie Freleng (Bone Valley Season 3: Graves County, Wrongful Conviction, Suave) launched a “live” investigation into David's conviction alongside Jason Baldwin (himself wrongfully convicted as a member of the West Memphis Three). Maggie had come to believe that the entire investigation of David was botched by the tiny local police department, or worse, covered up the real killer. Was Maggie correct? Was David’s claim of innocence credible? In Death and Deceit in Alliance, Maggie recounts the case that launched her career, and ultimately, “broke” her.” The results will shock the listener and reduce Maggie to tears and self-doubt. This is not your typical wrongful conviction story. In fact, it turns the genre on its head. It asks the question: What if our champions are foolish? Season 4 - The Burden: Get the Money and Run “Trying to murder my father, this was the thing that put me on the path.” That’s Joe Loya and that path was bank robbery. Bank, bank, bank, bank, bank. In season 4 of The Burden: Get the Money and Run, we hear from Joe who was once the most prolific bank robber in Southern California, and beyond. He used disguises, body doubles, proxies. He leaped over counters, grabbed the money and ran. Even as the FBI was closing in. It was a showdown between a daring bank robber, and a patient FBI agent. Joe was no ordinary bank robber. He was bright, articulate, charismatic, and driven by a dark rage that he summoned up at will. In seven episodes, Joe tells all: the what, the how… and the why. Including why he tried to murder his father. Season 3 - The Burden: Avenger Miriam Lewin is one of Argentina’s leading journalists today. At 19 years old, she was kidnapped off the streets of Buenos Aires for her political activism and thrown into a concentration camp. Thousands of her fellow inmates were executed, tossed alive from a cargo plane into the ocean. Miriam, along with a handful of others, will survive the camp. Then as a journalist, she will wage a decades long campaign to bring her tormentors to justice. Avenger is about one woman’s triumphant battle against unbelievable odds to survive torture, claim justice for the crimes done against her and others like her, and change the future of her country. Season 2 - The Burden: Empire on Blood Empire on Blood is set in the Bronx, NY, in the early 90s, when two young drug dealers ruled an intersection known as “The Corner on Blood.” The boss, Calvin Buari, lived large. He and a protege swore they would build an empire on blood. Then the relationship frayed and the protege accused Calvin of a double homicide which he claimed he didn’t do. But did he? Award-winning journalist Steve Fishman spent seven years to answer that question. This is the story of one man’s last chance to overturn his life sentence. He may prevail, but someone’s gotta pay. The Burden: Empire on Blood is the director’s cut of the true crime classic which reached #1 on the charts when it was first released half a dozen years ago. Season 1 - The Burden In the 1990s, Detective Louis N. Scarcella was legendary. In a city overrun by violent crime, he cracked the toughest cases and put away the worst criminals. “The Hulk” was his nickname. Then the story changed. Scarcella ran into a group of convicted murderers who all say they are innocent. They turned themselves into jailhouse-lawyers and in prison founded a lway firm. When they realized Scarcella helped put many of them away, they set their sights on taking him down. And with the help of a NY Times reporter they have a chance. For years, Scarcella insisted he did nothing wrong. But that’s all he’d say. Until we tracked Scarcella to a sauna in a Russian bathhouse, where he started to talk..and talk and talk. “The guilty have gone free,” he whispered. And then agreed to take us into the belly of the beast. Welcome to The Burden.
