Good To Know

Q: Does this guide come with the tensioner itself? A: This listing covers the tensioner guide only, so check your assembly to see whether the tensioner body also needs replacing. Reusing a worn tensioner with a new guide can shorten the life of both parts.

Q: How do I know the guide needs replacing? A: A scored, grooved, or cracked guide surface, or a rattling timing chain, usually points to wear. Confirm the part number 420236501 matches your engine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
