Check the antifrezze level first but only after the cars cooled down then check to see if the coolant fans are coming on after it warms up

Overheating and coolant boiling over while driving... cranking the heater helped... is it maybe just a sticky thermostat?


check thermostat but usually means you need head gasket job. check your engine oil and see if its mixing with antifreeze you will have to do compression test to be sure but it sounds like a head gasket in damage making car overheat heater on helps cool motor some but engine will eventually seize up driving it while overheating

2001 Pontiac Sunfire is dumping antifreeze out the overflow. Could it be something other than thermostat?


Common causes include: leak from engine, hoses, etc. causing overheat due to low coolant, electric fan not coming on, internally obstructed radiator, external obstruction to radiator (leaves paper. plastic bag on front of radiator of stuck between radiator and A/C condenser), bad thermostat and last, blown head gasket. Proper testing for any and all these conditions will give you the answer you are looking for. If the antifreeze is overflowing without any overheat, it can either be over-full, or in some cases, a head gasket can do this by filling the cooling system with exhaust and driving the coolant out.
