A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

    Water pump replacement requires removal of the fan belt,fan shroud,radiator(for extra room),fan and clutch fan assembly,possibly some pulleys and belt tensioner,and finally the water pump.Oh, and as always remove the ground cable from the battery.Possibly the positive cable too.

    after turn off water drips from under the hood. It's not fixed yet,because it needs a water pump.

    It leaves a tell tale "wet spot" in the driveway where I park. If coolant gets too low, it will overheat as indicated by temp. gauge or "idiot light".

    Th Fix....Replace the water pump. Consult your Shop manual for details.
