Good To Know

Q: Is this water pump impeller shaft w/ gear the same as the OEM part? A: Yes, it matches the dimensions and gear profile of the original Suzuki shaft, but it is an aftermarket replacement not manufactured by Suzuki.

Q: Do I need to replace the water pump seal at the same time? A: It is recommended to install a new water pump seal and gasket when replacing the shaft to avoid coolant leaks.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
