Blown head gasket i have the same problem. Pull the intake off and it mite be the intake gaskets if so get fel pro gaskets they will never blow again a nother way to test and see if the headgaskets are blown is put a compression tester on each cyl and see if they have different compression they mite be a few pounds different but that is normal if there is a big drop in pressure there is ur problem but check the intake first then go from there but i changed the intake gaskets and they where blown and i put it back togother and i still had the same problem but i took it apart yesterday and it was the head gaskets

Could be a few things - thermostat stuck shut?
Hole in radiator? cap not sealing? Blockage in block/hoses?
Water pump? faulty water temp gauge? check pressure of system by doing a pressure test and check for any leakage

My 99 grand am is overheating. I changed the thermostat and it still over heats. what else can cause it to overheat?


How hot does it get in degrees F? Does the radiator fan work? Some fans won't turn on till about 220 degrees F.
Could have blockage in radiator or engine block? Check the water pump. Your serpentine belt ok? Could be gasket issues? Any coolant in the oil or oil in the coolant. Check your coolant temp sensor. Don't replace anything unless your testing points in that direction. Are you losing coolant?

My Wife's care overheats and the heater only blows out cold air.


check that the thermostat is in correctly as it will cause no circulation but overheating. have a compression test done to eliminate head gasket /cracked head. There could be a blockage in the heater core but I am thinking that by passing the heater fan he has also by passed the actuator( coolant valve) for the heater core. Water pumps suffer from bad bearings and very seldom anything else. check that he hasn't blocked off the water to the heater core as well
the throwing back of the coolant is the boiling of the coolant in the block ( bad head gasket) due to lack of circulation. It may be a blocked radiator as flushing doesn't fix the blocked cores . If that is the case a new radiator is in order.
