Engine Cooling problem
1988 Chevy Blazer 4 cyl Four Wheel Drive Automatic 165000 miles
Ive had a water pump leak for quite some time. Yesterday it finally went out started overheating at a stoplight. Temp went from 210(norm) to 260 in seconds. I bought a new waterpump, thermostat and bolts and installed. Added new coolant to 3 1/4gal. Warmed up just fine turned off turned on again was fine. Let it run till it hit 210 (w/ heater on) temp kept rising slowly above 210. Turned heater off, temp went down below 210 then slowly started rising again above 210 again. I can't figure out what is causing it to overheat. Thanks
have the same problem?
