Engine Cooling problem
1996 Chevy Blazer 6 cyl Two Wheel Drive Automatic 119000 miles
I replaced the thermostat housing (it had developed a pin hole leak) and thermostat on my 96 Blazer, had the cooling system flushed.
After I did this, the engine temp gauge would steadily rise to around 240-250 for a few minutes then fall back to around 190 degrees. I checked the coolant resevoir and it is full, but there was not alot of coolant in the radiator itself.
I replaced the thermostat again and refilled the radiator. Same thing will happen. Tempature will rise to around 240 degrees, then fall back to 190 degrees in a few minutes.
Could I have another defective thermostat?
Could the radiator pressure cap be defective, not allowing coolant from the resevoir to flow back to the engine?
have the same problem?
