What it does

Belts and tensioners wear together, so they are often replaced as a set. 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.
• Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
• Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
