Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Chains last longer than belts, but guides and tensioners wear. A rattle at startup is a common sign they need attention. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Line up every timing mark before closing the cover, and turn the engine over by hand twice to confirm.
- Timing cover gasket and seal: The cover comes off for this job.
- Oil and filter: Fresh oil helps a new chain and hydraulic tensioner.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
