Product Overview
The water pump circulates coolant through the engine and cooling system to control operating temperature during normal and heavy-load use. Replace the pump when coolant leaks around the seal, the bearing becomes noisy or loose, or operating temperature begins climbing because circulation is reduced.
This part is a practical repair choice when the original component is worn or failed and the machine is showing problems such as coolant leaking from the pump or weep hole, rough or noisy pump bearing, pulley or hub play. Confirming the part number and application before installation helps avoid ordering a visually similar component that uses a different configuration.
