MOOSE RACING water pump repair kit for YAMAHA WR 450 F, YZ 450 F, YZ 450 FX from 2018 to 2023

MOOSE RACING offers this water pump repair kit for YAMAHA WR 450 F, YZ 450 F, YZ 450 FX from 2018 to 2023. 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 MOOSE RACING?

Moose Racing water pump kits combine gaskets, O-rings, bearings and mechanical seal depending on the model: the whole rebuild in one part number.

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

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.
