Hey guys, this one has me stumped. While i am driveing, even with the heat on full blast (the heat works good) my car over heats... i dont know why, could it be a bad temp sensor? But it still reads cold when the car has sat..

Any ideas

PS I dont check the board often so I might not reply for a bit...
but thatnx for any input

 

First of all, when it starts overheating, pop the hood and see if its actually overheating. If its too hot you will be able to tell, the air around the engine will be signifigantly warmer than normal. Check radiator and hoses for leaks and make sure your radiator is topped off. Check the radiator every few hours to see if its losing fluid. If its not, then it could be a bad thermostat. Make sure your fans are kicking in at the right times as well.

 

how bout the water pump?

 

I'd check your radiator / radiator fluid. If those are fine, I'd start to point a finger at the thermostat.

 

yes thermostat and check the main relays.
my radiator is losing fluid but the car doesnt overheat.

 

thanx guys, il check those out
