Engine Cooling problem
1998 GMC Sierra V8 Two Wheel Drive Automatic 240000 miles
engine was overheating, fixed leak in rad. Replaced tension pulley, replaced thermo, replaced cap. I am still getting a overheat problem. About 10 miles it starts to over heat, fills overflow. I get a lot of pressure when taking off cap, not a lot of water. After that I fill about 2 gal of water and is ok for 10 miles. I think it could be intake manifold gasket? After I shut off engine I get steam coming out exhaust pipe for a few minutes?
have the same problem?
