Installation Notes

Verify the vehicle’s year, make, model, and outer sprocket application before installation. Cloyes recommends replacing the chain tensioner(s), sprocket(s), and guide(s) when the timing chain is replaced, since these components work together to keep the chain properly supported and tensioned. Confirm bore size, tooth count, and keyway alignment against the application-specific catalog data before assembly.
