Good To Know

Q: What does the timing chain tensioner guide do? A: It keeps the timing chain aligned and tensioned so camshaft timing stays accurate. A worn guide can cause chain noise and timing drift.

Q: Should the guide be replaced with the chain? A: Replacing the guide alongside the chain during service is common practice for this engine type. Confirm the part number against your model 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.
