Installation Notes

Inspect the timing chain, guides, sprockets, and related wear surfaces before installation. Replace worn mating components as needed and verify timing marks during assembly. Because this kit does not list a tensioner, gaskets, or drive sprocket as included, confirm the required engine-specific parts before beginning the repair.

For best results, follow the factory service procedure for the exact Chevrolet, Buick, Oldsmobile, Pontiac, or Cadillac application. Proper timing alignment is critical to engine performance and long-term reliability.
