Well this car started off with a simple overheating problem, but 2 weeks later I'm here. I recently replaced the thermostat, hoping that would fix it. Well it didn't. Turns out I needed a ECT sensor as well which i didn't mind paying for cuz I knew I needed it cuz the gauges where acting weird and saying it was overheating when it wasn't. Well that did not fix the problem. I just had the radiator and engine block flushed out this morning and i don't know why but i think it made it worse. Now my car is overheating more quickly so now I'm stumped. I think it might be the radiator itself but then again the fans aren't kicking on from what i can see. They were working yesterday but i can't get them to kick on today. Anyone got any advice!?!?!?!?!? please reply...........

The coolant light kept coming on, and I kept adding coolant. I had the car pressure tested to find whee it was being lost, A new water pump ($400) was installed. It began to run hot after two weeks. It then began to leak on the carpeting. A new Heater core was the next solution. But since the idiots at GM put the core INSIDE the fire wall, it was a $700 repair. It still ran hot, so the thermostat was replaced. Then the radiator was hot at the top, and cool at the bottom. IT was also replaced, Total, $1341, plus towing. BUT that wasn't the CAUSE of all the trouble. It also needed a new head gasket! Another $1687!
