85 GMC C1500 Overheating
My sons GMC overheated last night and blew a hole in the radiator. We replaced the radiator, but it is still overheating. Not sure if this is related to the thermostat or the water pump. Is there a way to tell?
did you purge all the air from the new radiator? remove the thermostat and disconnect the top radiator hose from the radiator. start the engine for a second, if you get coolant out the hose its not the waterpump.
