Technical specifications

Installation requirements

Allow the engine to cool fully before draining coolant. Depending on the engine, replacing the pump may involve removing the drive belt, intake components or heat shields. Fit new seals, refill with the coolant type specified by the vehicle manufacturer and bleed the system thoroughly to remove air pockets. Check for leaks and monitor the temperature gauge on the first drive. Professional installation is recommended.

Fitment checks before ordering

Engine revisions changed the pump design over time. Confirm the correct pump by OE number or VIN before ordering.
