This PT Cruiser Has a Serious Problem

This PT Cruiser Has a Serious Problem

rev up your engine’s, okay here we go
you got an overheating car in this case
it’s a PT Cruiser, there are literally
dozens of things that can make a car
overheat so where do you start, well you
start with the most obvious things you
can find, and what’s in it okay it’s got
Bo 300 multiple misfires
it’s got PR 128 coolant thermostat below
regulating temperature, and again the
misfires and no definition found that
fascinating, but when we look over here
that’s for the TCM that’s for the
transmission control module so that
probably won’t have anything with the
engine overheating, we’ll ignore that for
the time being,
so the codes hey, the engine’s misfiring
but is the engine misfiring because the
engines overheating, or is something
making the edge and misfiring that
causes the engine to overheat
well that wasn’t all that much help so
let’s check the coolant level next, well
look inside here and lo and behold you
can’t even see the coolant so it’s low
on coolant, now there’s a whole bunch of
reasons you could be low on coolant
leaking radiator cap, leak in the system,
overeating engine but since this engines
cold here’s a quick test, what you can
do is start the engine up cold with a
cap off, then put your hand over the
radiator cap hole, now I don’t feel
any pressure coming out, so the ehad gasket
isn’t completely blown, if my
hand would of had a lot of pressure
coming out on an ice cold engine when
you started it where you remove the
radiator cap from, that would mean the head
gasket is so far gone it’s just blowing
smoke up through there and you know the
engine would need work, but in this case
that’s not happening so, for the time
being we’re just gonna put some water in
the system to check for leaks, now while
we’re doing this we’re gonna turn on the
a/c full blast to see if the cooling fan
works then, here we go
I can feel the cooling fan blowing really
strong, so we
know the cooling fan works fine with the
AC on,
but sometimes the cooling fan does not
work right when the AC is off, their two
separate systems, because when you turn
the AC on it’s supposed to turn the
cooling fan on the radiator on to suck
air through the radiator and the AC
condenser that’s in front of the
radiator so the AC blow cold, but
when you’re driving a car with the AC
off it’s a different system and that works
that when the sensor for that system
sees the temperature gets to a certain
amount of degrees, it’ll turn the cooling
fans on and then when it cools down they
go off, and then when it gets hotter
again it’ll go on, so I’m going to turn
the AC off now and let it idle and see
if the fans come on and off, this might
take a little while but hey that’s the
life of figuring out why your car is
overheating, so we’ll turn the AC off and
now we’ll go to the fan here, stick our
hand behind it and we don’t feel it
it’s not moving, so now we have to wait
for the engine to warm up, now here’s the
temperature gauge once it starts to warm up
we got a watch to see that those fans
come on, it’s a very common problem with
these things that the original system
doesn’t turn the fans on, now while we’re
waiting for it to warm up here’s a tip,
let’s say your car starting to overheat
especially in traffic and if you turn
the AC on and it stops overheating and
the temperature goes back down,
hey just drive around with the AC on
at least for the interim you’re not hurting
anything, this may or may not be the
problem we don’t know, we gotta wait
until the car warms up to see if that
cooling fan comes on by itself with the
AC off, now while we’re waiting this is
the time that you need to know
everything about the car possible, in
this case I asked the customer he said
the car was wrecked in the front
some body work done and some radiator
work done, it could easily be they messed
with the sensors that turn the cooling
fan on it could be the whole problem, but
we gotta wait until we see whether it comes
on or not, because if it comes on well
that’s not the problem, well
the temperature gauge is starting to get a
higher so let’s go under the hood and
see what’s happening with the fan, I hear
something and lo and behold it’s on, so
that system is working, the fans coming
on, well now what are we gonna do now I
gotta figure out why is it overheating,
well I just figured one thing out the
fan just kicked in full blast you can
hear them and when I put my hand behind the
radiator fan it’s blowing like mad
but it’s cool air, that should be hot air
so for some reason the radiator isn’t
getting enough hot water in it, and just
and yes now it’s starting to overheat to get
it into the hot zone so we’ll turn it off,
so I’m gonna
get this little temperature tester out and
it was 19 bucks or so we’re gonna try to
find where there’s a restriction to keep
the water from getting into the radiator
so it’ll dissipate the heat with a fan,
we’ll take a few temperature readings
the top is 199 but the bottom here
is only 108, so the water not coming
from the top to the bottom, and guess
what the thermostat is in here, so we’re
just gonna change the thermostat let’s
pray it’s that cheap of a fix, so we’ll
move some stuff out of the way and unbolt
the thermostat, and there’s a
stupid thing, this is supposed to be
closed when it’s cold
and open when it’s hot, you saw it
getting hot it didn’t open so we’re
gonna replace the thermostat, now when
you put the new thermostat in you got to
make sure that the knotch goes the right
way, there’s a notch right here fits
right in, as you can see right here it
fits right in the notch it’s nice and
tight and it won’t fall out when you put
it back in, then you tighten the housing
back on, and we’ll fill it full of
coolant, put the cap back on
nice and tight, then start it up and see
what father time he has to say about it
ehating after it warms up
remember there’s no shortcuts when it
comes to time, you gotta let it run till
it warms up, then see if the fan comes
on, if it does
odds are it’s fixed, you still need to road
test it for half an hour so you see how it
does on the highway, but it was overheating
just idling before and if it stops now
that should be it, and here we go
I hear the fans coming on, and when I
stick my hands in, the air is blowing and
this time it’s warm air, it’s not cool
air, it means it’s actually circulating,
and as we can see on a temperature gauge
look it’s staying pretty much around the
middle it’s not going up to the H
like it was before, so if you never want

videos, remember to ring that Bell!

  2. Very odd question for you, Scotty, is there any left foot drive conversion kit out there for manual cars?

  4. This was my first car… mad overheating and blown head gasket after 4 months. Wish I discover this channel earlier 😩

  5. Hi Scotty I'm in nz and just did timing belt, front seal, rear seal, clutch etc on a 2000 2.0 cruiser. How the heck do you bleed the master cylinder for the clutch on these bloody things?????

  6. I would have run a flush through the cooling system before replacing the thermostat or refilling the coolant. I’ve often found silicates from the old coolant collect in the bends and cavities of the passages.

  7. I saw those wrenches jump and rattle on top of the engine when you started it todo your fixit test………………. hahaahah that could've been nasty

  8. I cringed when I saw you start the engine with tools on top of it and that sucker jumping like a rabbit lmao

  9. Thank you for sharing this video. If they only made the pt cruiser twice the size I would have bought one.

  10. That was a fabulous blow for blow diagnosis. JUST GREAT! That pistol type temperature sensor was the bees knees. I don't remember that at Harbor Frieght!

  11. Hmm.. So it was the thermostat..
    my car has an overheating problem too I wonder if it could be that🤔

  12. Careful don't put your fingers in The fan LOL.the back of the blades would probably just bounce your fingers away and not cut them but still it will startle you.


  14. There's no freaking way I can over-compliment you. Every single vid of yours I've seen is 1st class. Thanks again.

  15. Had an early Cruiser that need a water pump. Some mechanics wouldn't even quote it and I found out why. The book lists the labor at 7 hours and after I saw what you had to do to change it, I don't blame them. LOwest estimate I got from a guy we have used before was 950-1100 dollars for a car that was worth 400. Tow truck payed me 200.

  16. We owned a 2001 Chrysler PT Cruiser & I think everything that could go wrong did go wrong with that car. The PT was easily the worst car we ever owned. I also had a 1991 Dodge Spirit & it was also bad, I will never buy another Chrysler product.

  17. One thing I learned about a head gasket blowing was with my 1997 Outback. Sitting and idling, the coolant stayed in the radiator, even with the cap off. If I put my foot on the brake, put it in gear, then stepped on the gas while holding the brake, then the coolant would blow out of the radiator like a geyser. It was only doing it while the engine was under load. This was with the first generation EJ25 engine, which was notorious for head gasket failure around 100k miles.

  18. They have a glaring problem that starts with “c-h-r-y-s-l-e-r” and ends with the car overheating and falling apart, not necessarily in that order

  19. Your new style, general topic videos are great, but these old fashioned repair/diagnostic videos that made you famous are best! P.S. Please give more thought regarding the title of your videos. For example, this one should be called: "PT Cruiser thermostat diagnosis", or something like that. More descriptive titles would allow your videos to be found easier, increasing your viewership.

  20. Scotty – great video. Please please please make more videos like this for those of us who want to learn! Thanks dude!!!

  21. My Australian PT cruiser is a 2005 Model, I've had it for over 5 1/2 years and it has never missed a beat, nothing has ever gone wrong with it at all.

  22. My cruiser had this problem. Same convertible 2.4 turbo. It does better with a new radiator cap but when the A/C is ON it gets hot. Off it’s fine and when the heater is on it’s fine. :/

  23. Pretty typical early 2000s Chrysler product with the 2.4 mine was the thermostat as well and same with my aunts Jeep, good thing they got to it before the head gasket blew

  24. Hello Scotty…My Pt Cruiser consume a lot of antifreeze, I change my radiator cap because was a old one, just in case but still. I heard that on hot days that happen especially when you use 50/50 antifreeze, the water evaporate easy. Tell me what can I do…I like my car and I don`t want to lose it.

  25. Hi, my pt cruiser overheated and stalled when driving. (Left the radiator cap off!) Now it will crank slow but doesn’t start! I just had the battery replaced and no clue! Any idea?
