URO PARTS Timing Chain Tensioner - 11-31-7-557-741

A rattle from the front of the engine, especially on a cold start, a check-engine light with camshaft or crankshaft correlation codes, rough running, or reduced performance.

Yes. The chain, guides, rails and tensioner wear together, so replacing them as a set avoids repeating a labor-intensive job. Replace any single-use bolts and seals disturbed during the work.

On many engines the valves and pistons share the same space, so a jumped or broken chain can cause severe internal engine damage. That is why early signs like cold-start rattle should be investigated promptly.

It requires engine-specific locking tools and precise timing procedures, and errors can damage the engine. It is best done by an experienced technician or a well-equipped enthusiast following the factory procedure.
