ok ive tried that now a couple different ways and its a no go. interesting note is that it builds alot of pressure on the uppper radiator hose but i ran a compression test on it and all four cylinders are getting to 75 is that normal or should i be pissed off? i ran a coolent pressure test and it held fluid. and i beld the shit out of it but it still has the problem. the thermostat is changed, and my fan clutch and water pump are new. any ideas?
