Detailed Description

The Gates Accessory Belt Drive Kit 90K-39359D is a service solution for the serpentine belt drive system on select Subaru models. By replacing the belt and tensioner together, the kit helps restore proper belt tracking and tension control across the accessory drive. The belt measures 85.455 inches outside circumference and 20 mm in top width, and the kit is identified by belt part number K060849 and tensioner assembly 39359.

For Subaru Impreza, Subaru XV, and Subaru XV Crosstrek applications, this kit supports a more complete front-end accessory drive repair than a belt-only replacement. It is a practical choice when servicing a noisy, worn, or aging serpentine drive on 2012-2014 Subaru Impreza or 2013-2014 Subaru XV and XV Crosstrek models. This part cross-references Gates (e.g., 90K-39359D) for the same application.

Common Problems This Kit Helps Address

• Squealing or chirping from the serpentine belt drive
• Visible belt wear, glazing, or cracking
• Weak or noisy belt tensioner operation
• Uneven belt tracking caused by worn drive components
• Repeat belt replacement caused by leaving aged tensioning parts in service

Installation Notes and Tips

Verify the vehicle year, model, and accessory drive configuration before installation. Compare the existing belt length and tensioner assembly to the listed specifications: belt K060849, tensioner 39359, and 85.455-inch outside circumference. Follow the included installation instructions and tech tips for accurate routing and proper tensioner setup.

For Subaru Impreza, Subaru XV, and Subaru XV Crosstrek service, inspect the full accessory drive path for wear before final assembly. Replacing the belt and tensioner together helps complete the repair on the first service visit.

Quality Assurance

Gates manufactures this accessory belt drive kit as an OE-equivalent service part for the specified Subaru applications. The kit is packaged with application-specific components and installation guidance to support accurate repair of the serpentine drive system.
