Detailed Description

Gates 39396 is a premium automatic belt tensioner assembly for accessory drive belt systems that require OE-level dimensions and operating characteristics. The tensioner is manufactured to rigid tolerances and specifications to support proper belt tracking and consistent belt tension in V-ribbed belt applications.

What It Helps Address

Installation Notes and Tips

Verify belt routing, pulley alignment, and mounting-hole location before installation. Inspect the accessory drive belt, idler pulleys, and related components for wear at the same time, since a new tensioner performs best with a belt system in good condition. Confirm the OE Exact dimensions and application match the vehicle before service.
