I'd say this pump has had better days!!! New radiator and water pump going back in with rebuilt head on Red.
ERNIE BEFORE YOU START THE FLUSH ING BE CERTAIN THAT THE HTR VLV ON THE DASH IS SET TO FULL HOT , PROB WOULD NOT BE A BAD IDEA TO REMOVE BOTH THE HTR HOSES AND HOOK THEM TO GETHER AND FLUSH THE ENTIRE SYSTEM MINUS THE HTR CORE AND THEN DO THE CORE SEPERATELY, SO IT DOESNT GET PLUGGED UP.sassee said:It had 4ZE1 stamp on the pump..................thinking it could very well be the original one! But it will def be flushed. Don't want to do this again any time soon.
