Good To Know

Q: Does this guide come with the tensioner itself? A: This listing covers the tensioner guide only; the tensioner body is a separate component, so inspect both during service.

Q: Can I replace just the guide without pulling the engine? A: On many 1503 platforms access is tight, so check your service manual for the correct procedure before starting the job.

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