Why does your 96 Chevy Lumina LS overheat?

Answer 1

one option is that the thermostat is sticking, and that wont let the coolant circulate. if the coolant cant circulate, it will overheat the engine. also there could be a plug in the line somewhere which also will not allow the coolant to flow properly. If there is a plug, it can be dislodged by accelerating hard to force the coolant through. also, when the car starts to heat up, check under the hood to see if the fans are running. If all fails, check for intake manifold gasket leaks, hose leaks, and oil leaks, Be sure all fuses are working and in good condition. Simple overheating conditions are usually caused by bad fan fuses. You'll know if the fans are working when the A/C is turned on, If the fans Do Not turn on then it needs to be checked.
