Installation Notes

Verify engine code and application details before installation, especially on vehicles with notes such as Engine VIN A. Inspect the timing cover, sprockets, and related wear surfaces during service, and replace any damaged mating components as needed. Because this kit does not include a tensioner, gaskets, or a drive sprocket, confirm the engine’s required parts before beginning the repair. Professional installation is recommended for timing system service.
