Specs At A Glance

Good To Know

Q: What are the signs the timing chain guide is worn? A: Chain rattle at idle, rough running, or a loose chain during inspection point to a worn guide that needs replacement. Verifying against OEM number 420236501 confirms the correct part.

Q: Should I replace other timing components at the same time? A: It is common to replace the chain and tensioner together when servicing the guide on the 1503 engine. Serving them as a set avoids repeat labor down the road.

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