PT Cruiser

Car Information:
Chrysler PT Cruiser
Year: 2004
Engine Size: 4 cylinder
Trans: Automatic

Issue / Question:
When stopped at a traffic light or in traffic, the engine will start running rough, AC stops blowing cool air and engine begins overheating. I also notice what seems to be some warm extra humid air coming out of the ac vents inside the car. Once I am rolling again at 45 plus mph everything returns to normal.

I have had the cooling fan replaced twice, first a little over 2 years ago and they also recharged the ac at that time. They said the humid air was probably refrigerant being forced out of the ac system through some kind of pressure relief valve. The car ran fine after this for a little over a year.

The second time was about 6 months ago which again worked for a few weeks and then the same problem started over again. When I took it back they found a problem with the wiring harness going to the fan and replaced the wiring harness, fan, thermostat and flushed the cooling system. This time they told me the ac system was fully charged and there was no need to recharge the ac system. The car has been fine for the last 5 months but now the problem is starting again. What could be causing this problem? In doing online searches I have seen where this seems to be a problem with PT Cruisers but I have not found any definitive answers as to what the cause and fix is. Any information and direction you can provide would be greatly appreciated.

Answer:
If the cooling fan is running, sounds to me like you may have a heater core leaking coolant slowly, and when it gets down so low the engine starts to overheat causing the A/C to switch off and that would also explain the humid air inside the vehicle.

Chrysler/PT Cruiser Mechanical Issues

Car Information:
Chrysler/PT Cruiser
Year: 2003
Engine Size: Unknown
Trans: Automatic

Issue / Question:
My car overheats. The radiator, heter core, and oil cooler have been replaced. The engine was replaced about ome year ago. Visually, there is brown colored csudge in the colling system. My mechanic took out the thermostat and advised me not to have one. In addition, he advised not using cooland because it is not needed in our climate. The oil seems not to be watery; hence, I doubt that the head gasket is blown.

Any ideas?

Answer:
Find a new mechanic from what you have stated so far. This guy is clueless and full of bad advice!

Chrysler PT Cruiser Cooling System

Car Information:
Chrysler PT Cruiser
Year: 2002
Engine Size: 4 cycle
Trans: Automatic

Issue / Question:
My car has 103,000 miles. It overheats after driving about 5 miles. If the car is started and left to idle, it will run right smack in the middle of the temperature gauge. Drive with or without the a/c on and it goes up to the limit headed to red, so we shut it down. The person I bought this car from recently blew a head gasket, but it was repaired at a reputable shop and all is well with that.

These things were done recently and the new radiator is at 96,000 miles by the previous owner.

Since it has been over heating on me, I have bled the cooling system, flushed and bled the cooling system, replaced the thermostat and bled the cooling system again, replaced the coolant temperature sensor and finally bled the coolant system.

Today, took the car to a shop for a diagnostic. The service writer says I need a new radiator fan because the motor doesn’t work on high speed. Took the car home and jump-wired the fan directly to the battery on both high and low speed side, worked perfectly. I then replaced the high speed relay and she still runs hot.

What else can it be?

Answer:
I would do a block test to make sure there isn’t compression gases getting into the cooling system and causing an air pocket at the water pump! If it passes the block test I would pull the timing cover, mark the water pump pulley, start and rev the engine while using a timing light, and see if the timing belt is slipping on the water pump pulley!

Timing Belt on PT Cruiser

Car Information:
Chrysler PT Cruiser
Year: 2001
Engine Size: 2.4 4 cylinder
Trans: Automatic

Issue / Question:

The car only has 38K miles on it. My question is do I need to change the timing belt as the manual says to change after 8 years or 120,000 miles. Given the minimal usage, am I at risk by not changing it yet?

Thank you very much.

Answer:
A 9 year old timing belt is like a 9 year old tire! I don’t trust either one!

Anti- Freeze

Car Information:
PT Cruiser
Year: 2002
Engine Size:
Trans: Automatic

Issue / Question:
My last oil change indicated my anti-freeze level was ok. I have driven approximately 1000 miles since then and my radiator overheated. It was about 1/2 gal of anti-freeze low. I can not see where any leaking has happened. What should I do?

Answer:
We would suggest a flow test to make sure there is no restrictions then a pressure test and if no external leaks are found, we would run a block test to see if compression gases are entering the cooling system.
