Installation Notes

Verify engine configuration and accessory belt routing before installation. Replace the rubber seal ring during service and inspect the belt, hoses, and mating surfaces for wear or contamination. Confirm that the pump orientation matches the standard rotation and that no pulley, thermostat housing, or back housing is required for your application.
