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 250 F, YZ 250 F, YZ 250 FX from 2019 to 2024. 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.
Check the exact model and year of your bike in the list below before ordering.
