BOYESEN water pump cover and impeller kit for YAMAHA WR 450 F, YZ 450 F, YZ 450 FX from 2014 to 2023

BOYESEN offers this water pump cover and impeller kit for YAMAHA WR 450 F, YZ 450 F, YZ 450 FX from 2014 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 BOYESEN?

The Boyesen SuperCooler pump replaces the stock plastic impeller with a patented aluminium one, claimed by the brand to be 25 % more efficient.

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.

Specifications and fitting tips

• Material: Aluminium
• Patented Nautilus-style cast aluminum impeller
• Cover and impeller kit to increase coolant flow at all engine speeds

Cross-Mania tip: Drain the system before working on it, refill with fresh coolant and bleed the air.
