2005 PT Cruiser overheating while idling
I know you all will probably tell me I am wasting time and money but here it
goes. I have replaced the radiator, fan, radiator cap, thermostat, temperature
sensor, temperature sensor wiring harness, low speed fan relay and it runs
fantastic until I get home. In less than five minutes of idling it overheats. I can
hear the fans functioning properly. I would have sent it off to junk for Jesus but
my 10 year old son ababsolutely loves the car. It's his little Meep Meep (the
sound the horn makes earned it his nickname)
Still sounds like a coolant flow problem. When was the water pump replaced? It may have bad impellers. Also have you had a block check performed?
You could try installing a heavier duty radiator. I would first try a bottle of Water Wetter in the coolant which should help reduce heat build up.
a question ? will a clogged cat cause over heating
