Engine Cooling problem
1992 Chevy Truck 6 cyl Two Wheel Drive Manual 296000 miles
recently my truck started getting hot. I've gone through the whole cooling system and replaced everything but the engine i.E. ( Water pump, radiator, termostat, flushed the system ect. )
Yet when I start the truck and let it come up to tempature I've noticed that the raidiator overflow tank starts filling and then starts blowing water out untiil so much water leaves the system that it overheats. Also during this process the raidaitor hose has so much pressure on it it feels like a inflated tire i.E. ( Cannot pinch the hose because there is so much water pressure ). Note I have also checked to make sure there is no water vapor coming from the engine exhaust, there is no oil in the water or water in the oil system. Help Is it possible that the head is cracked somewhere allowing piston compression into the water system? Or a head gasket leak? My next test is going to be a compression test on all cylinders to see if any are lossing compression
have the same problem?
