PROX Water Pump Repair Kit for YAMAHA YFZ 450 2009-2025

PROX offers this water pump repair kit for YAMAHA YFZ 450 2009-2025. The water pump moves coolant between the engine and radiators. Its shaft turns constantly and its seals wear: coolant eventually leaks, often from the small weep hole under the pump.

Why rebuild the water pump?

The benefits:

• Stop a coolant leak.
• Prevent engine overheating.
• Much cheaper than a complete pump.

Why choose PROX?

ProX, the Dutch engine-parts specialist since 1975, has its parts made in factories that also supply the manufacturers: OEM quality at a more affordable price.

When should you replace the water pump on your YAMAHA YFZ 450?

Check the weep hole under the pump and the coolant level regularly. A pump bearing with play quickly wears new seals, so replace them together.
