Before the water pump repair work was carried out, there were indications that the coolant was constantly decreasing and the coolant was constantly leaking from the pump over-block. If left unchecked, this would cause engine failure.
The steps taken were to remove the water pump from the engine drive.
Every system was checked, including the pump block, bushing, impeller, shaft, bearing, nock seal, mechanical seal, and O-ring seal.
After the inspection was completed, cavitation occurred in the mechanical seal, a component in a pump construction that functions as a barrier or blocker for the flow of coolant.
The repairs performed included replacing the bearing, O-ring seal, nock seal, mechanical seal, and packing.
After all replacements were completed, the water pump was reassembled and reassembled.
