If you have noticed your Pt Cruiser overheating, don't worry, your not alone. This is an extremely common problem with this model from Chrysler.
Things You Will Need
(Possibly may need):
New Thermostat and Gasket
New Radiator Cap
New Water Pump and Timing Belt
New Fan Motor
New Fuses/Relays that control fan
Step 1When you first notice your Cruiser overheating, you need to immediately check the coolant level of your car. Low coolant could be the obvious culprit here, but be careful when if you are taking the radiator cap off! It will be hot for a while after you shut off your car!
Step 2If adding coolant doesn't help, you might have either a serious situation or a simple-fix situation. Two cheap tweaks will include changing the radiator cap (it may be faulty, and causing your radiator to malfunction), and/or change the thermostat and gasket. These are two common fixes
Now, if none of the above changes help, your looking at a serious, and often costly problem. It could be three things: bad water pump, dead fan motor, or a crack in the head of your engine. These will all be over a hundred dollars to fix.
Step 4If your radiator is warm, then you most likely have a crack in the head of the engine, which is the most expensive at around 1600$
The third problem has been a prominent problem with ALL models and years of the Pt Cruiser. If you start your air conditioner, you should hear the low speed fan come on. This will happen whether your car is cold or not. You also have a high speed fan for when your car gets really hot, but both fan speeds shut off after the car is over 35 mph due to the wind flow cooling off the car. Sometimes the low speed works fine, but the high speed does not, so you have to replace the high speed fan motor only, which will cost around 100$ just for the parts. It's about a two hour job on your own, and you will have extra charges if a mechanic changes it for you.As mentioned before, this car has a history of problems, so if you happen to have purchased one without knowing about these issues-you have been warned!! Prevent this from happening by taking good care of the engine and car.
