BOYESEN water pump cover and impeller kit for YAMAHA WR 426 F, WR 450 F, YZ 426 F, YZ 450 F from 2000 to 2015

BOYESEN offers this water pump cover and impeller kit for YAMAHA WR 426 F, WR 450 F, YZ 426 F, YZ 450 F from 2000 to 2015. 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 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.
