Specs At A Glance

Good To Know

Q: Does this replace the OEM guide exactly? A: Yes, it is built as a direct replacement matching OEM part number 420236501 in fit and function. Always confirm your engine's part number before ordering.

Q: Should the guide be replaced with the timing chain? A: Guide and chain wear together, so replacing both at once during a timing service is common practice. Inspect the tensioner assembly at the same time.

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