• Service needs during timing chain, guide, or sprocket replacement

Installation Notes

Install 9-5658 in the right upper timing chain position only where listed in the fitment data. Verify engine application, position, and OE reference before installation. Because this tensioner uses an activation pin, follow the service procedure for proper release after mounting. For timing system repairs, inspect the chain, guides, and sprockets for wear and replace related components as needed.
