The kit that rebuilds the water pump, the part that circulates coolant through the engine.
MOOSE RACING offers this water pump repair kit for YAMAHA WR 450 F, YZ 450 F from 2006 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.
The benefits:
Moose Racing water pump kits combine gaskets, O-rings, bearings and mechanical seal depending on the model: the whole rebuild in one part number.
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.
Cross-Mania tip: Drain the system before working on it, refill with fresh coolant and bleed the air.
