Installation Notes and Tips

Confirm the vehicle year, make, model, and front-position application before installation. Inspect the camshaft sealing surface and surrounding components for wear, scoring, or contamination before fitting the new seal. Proper alignment and careful seating are important to avoid damaging the sealing lip during installation. Verify that the seal is installed in the correct front location for the engine configuration.
