ATHENA water pump repair kit for YAMAHA WR 450 F, YZ 450 F, YZ 450 FX from 2018 to 2022

ATHENA offers this water pump repair kit for YAMAHA WR 450 F, YZ 450 F, YZ 450 FX from 2018 to 2022. 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 ATHENA?

Athena water pump kits are designed and made in Italy by an original-equipment supplier to KTM and Ducati.

When should you replace the water pump on your YAMAHA YZ 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.
