Frequently Asked Questions

Q: Does this kit include the water pump shaft?
A: No, this kit includes the seals, bearings, and gaskets. If your shaft is heavily grooved or damaged, it should be replaced separately to ensure the new seals function correctly.

Q: How do I know if my water pump needs a rebuild?
A: The most common sign is coolant dripping from the "weep hole" located on the bottom of the water pump housing, or finding "milky" oil, which indicates coolant is bypassing the internal seal.

Q: Does this kit work for the 2024 models?
A: Yes, the 821585 kit is verified for all Suzuki DR-Z400 models through the 2024 model year.
