Detailed Description

The Gates 90K-38486 accessory belt drive kit is engineered to restore the serpentine drive system with matched service components. Replacing the belt alone can leave worn tensioning or pulley components in place, which can shorten belt life and contribute to repeat repairs. This kit addresses the belt drive as a system, using a belt with 2301 mm outside circumference and 24 mm top width for the listed Toyota applications.

This part cross-references Gates 90K-38486 for the same application.

Common Problems This Kit Can Address

• Squealing or chirping from the serpentine belt area

Installation Notes and Tips
