Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Squeals, cracks and glazing mean the belt is worn; a noisy tensioner or pulley means its bearing is going. 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
- Check the belt routing diagram before removal and inspect every pulley for play.
- Tensioner and idlers: Worn pulleys ruin new belts.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
