hey all

i was hoping you may help me with this tough overheating problem. It overheats with in 10- 15 min driving or idling. upper and lower hoses start off hot/warm, but 15 min later the bottom hose turns cold as does the radiator except for the cap and the overflow which is boiling. the heat in the cabin also goes off after 15 min. here is what i have done: new thermastat x2, new head gasket, new radiator and cap, new belts. I have burped it many times with the front end 3 ft in the air. there is no oil/coolant mix or white smoke from the exaust. fans do turn on, but are cooling a cold radiator. thanks for any of your suggestions

Are you sure you aren't putting in the thermostat backwards or something weird like that? Try running the car with no thermostat...no good for normal driving, but it could help narrow down your problems.

i have ran it with out the thermostat and it still got hot just about 10 min later, but when it did overheat the radiator was hot as was the bottom tube. thanks
