If you replaced some of theses already ignore and go down the line # Not enough coolant # Water pump drivebelt defective or out of adjustment # Radiator core blocked or grille restricted # Thermostat faulty # Electric cooling fans blades broken or cracked # Radiator cap not maintaining proper pressure # Ignition timing incorrect
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
Be care-full my radiator blew up and burnt me. I replaced Radiator, thermostat, and water pump. Timing belt is in the way so I replaced it too. OK Now
fan clutch?
did you replace radiator hoses i have seen hoses collapse and cause overheating while driving and radiator could be clogged. also did you bleed your cooling system according to owners manual
If the radiator or reservoir cap is bad it could cause overheating because the system will not build up the proper pressure. Also the fan clutch could be worn out which would keep the fan from spinning fast enough to cool the radiator.
Is your fan coming on?

If your PT Cruiser is still overheating despite replacing components in the cooling system, check for possible issues like a blown head gasket, which can cause bubbles in the radiator. Additionally, ensure that the thermostat is functioning properly and that there are no air pockets trapped in the system. A faulty water pump or radiator obstruction might also be the culprit. It could be beneficial to perform a pressure test to identify any leaks or weaknesses in the cooling system.
