Question about 2003 Hummer H2
My hummer h2 2003 is overheating when I stopping for 30 minutes and when i press the accelerator it's back to normal
This sound like either the fans or fan is not coming on or not performing like it should, or coolant system is clogged or low on coolant. if you have electric fans turn the a/c on are they both on ? if you have a clutch fan attached to the motor when the a/c on and engine at operating temp put your hand over engine is the fan realy pushing air out? if not its bad . you can check the temp of each side of the radiator to see if the is a difference this will tell you if their is a clogg. so check fans and check coolant system for a leak , for proper circulation , when was the last time you had the coolant system flushed ? and gm uses a different coolant then other makes if someone put regular green in with the dexcool it will become corrosive and can eat blades on water pump not allowing it to function like it should pumping coolant andit will clogg the system.
