The unit circulates engine coolant through the block and radiator to maintain proper operating temperatures. It is supplied as the pump assembly only, without the volute housing, and includes the mounting O-ring and bolts. Water pumps are typically replaced when they develop leaks, become noisy due to bearing failure, or during an engine overhaul to prevent overheating.
