The kit that rebuilds the water pump, the part that circulates coolant through the engine.
BOYESEN offers this water pump repair kit for KAWASAKI KX 250, KX 450, KX 450 X 2019-2024. 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.
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 KAWASAKI KX 450?
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.
