CHRYSLER PT CRUISER THERMOSTAT PROBLEM

2007 Chrysler PT Cruiser • 4 cylinder 2WD Automatic • 70,000 miles

My Chryler PT cruiser is overheating and then returning to cool. The air conditioner makes the car hesitate. The heat will not blow air. Antifreeze is coming back up out of the thermostate. What is the problem?

Coming back up out of the thermostat? Is the housing broken or missing? IS a bypass or temperature sensor missing?

Overheating and returning to cool. Does this happen with the engine still running, or do you have to shut the engine off?

Try removing the thermostat and flushing the cooling system. Then replace the thermostat and gasket, being sure to completely clean both thermostat housing mating surfaces.

The AC uses horsepower, so it can cause a slight hesitation or loss of acceleration.

The engine returns to cool when you cut it off and turn it back on.

Ok. The thermostat could be stuck closed. The water pump could be bad, not pumping water. Or, the radiator could be plugged. Or, a combination of the above.
