Installation Notes and Tips

Verify engine code, production date, and primary-pump application before ordering. Compare the pulley dimensions, impeller size, and mounting points to the original part on the vehicle. Replace the gasket during installation and inspect the cooling system for contamination, hose wear, and thermostat condition before returning the vehicle to service.
