Specs At A Glance

Good To Know

Q: Do I need to replace the thermostat at the same time? A: It is good practice to inspect the thermostat and coolant hoses while the pump is off, since a failing thermostat can mimic pump symptoms.

Q: Does this pump come with a gasket? A: Check the listing details for included hardware; many installers apply a fresh gasket and sealant to the mounting surface during installation.

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