Belts, tensioners and pulleys seldom break, rather they wear down over time. Tensioners, pulleys and belts need to be checked at 60,000 miles and replaced at 90,000 miles. Belts and tensioners wear at the same rate. We recommend that you change these components together at the same time - every time. Duralast Serpentine Belt Kits come with everything you need to get the job done.
  • Designed for OE Form Fit and Function
  • Kit includes belt(s) and all necessary drive components
  • One kit specifically made for your vehicle
  • Belt Routing Diagram included

    This is not a “Serpentine Belt” kit. It is an Air Conditioner Belt and Tensioner kit. AutoZone needs to correct this.

    Plastic pulley broke after 4 days. Don’t buy this. Find an OE steel pulley tensioner.

    Bought the kit in March and it broke in August. Very few miles were driven on the truck. Tensioner spring housing cracked, seized in position and spun the belt. Very poor quality
