Changed the heater core this week after it let go, after installing the new one, I filled up the cooling system (also replaced the thermostat) and drove the car, the temperature rose to normal operating and then the coolant started to back out through the expansion tank. This happened several times and then the engine went high temp. I changed the thermostat again and suspected maybe no water was getting in the engine. Took the top hose and filled the radiator reinstalled, same result water boiled out of the expansion tank, what other possibilities are there? Bad water pump? Radiator? Help. Thanks dennis
have the same problem?
