If your water pump failed and it was replaced, thats only 1/2 the replacement job. The debris removal from the broken impeller is CRUCIAL as it can circulate through the engine and cooling system. When this happens if debris blocks a cooling capillary inside one of the cylinder heads, the area will gain a hot pot and will crack. This occurs without any symptoms, no overheating and no temp elevation on the gauge.
Was the cooling system cleaned extensively?
These engines NEVER blow head gaskets (never seen a single one) and the heads WILL CRACK before a gasket blows!

Hi, in addition to changing the water pump, they flushed the coolant with BG Cooling System Cleaner. How do you remove the debris from the broken impeller?
