Having problems with your 2004 Hyundai Elantra ?

I have had my radiator replaced twice because my car started running hot. Now if my car idles too long the temp will go to hot. I have added more anti-freeze to the radiator but I never see anything leaking on the ground when it is parked. Could it be something else causing it to do this. I went to auto zone and was given a printout that it could be the thermostat.

Answers :

Possibly a blown head gasket. Take off the radiator cap and run the engine--are there any bubbles coming up in the coolant? Check the exhaust pipe--is it steamy or does it smell like anti-freeze?
I'd agree about the thermostat being the most likely cause. Pitty the workshop didn't look at the most likely cause before giving the bill for new radiators! Regards Johngee
