Having problems with your Cars & Trucks ?
I have a 2002 Pontiac Aztek and it is overheating. The heads and head gaskets were replaced 2 years ago, i have just replaced the thermostat and it ran a whole day without any problems but the next day after it sat overnight it started overheating again. It has heat and then no heat and the temp gage bounces up n down. I have checkrd the coolant levels and they are where they are supposed to be and i cannot find any leaks anywhere. I am stumped with what to look for next. Help please.
