Good To Know

Q: What does a water pump seal kit do? A: It replaces the sealing elements in the mechanical water pump so coolant stays inside the system instead of leaking past the pump shaft. This kit is built for the CRF450L application listed.

Q: Should I replace the seal kit if I see coolant weeping? A: Yes, coolant weeping at the pump area usually signals worn seals. Replacing the seal kit is the standard fix before overheating or coolant loss gets worse.
