Product Details

The Gates Accessory Belt Drive Kit line is built to restore the full serpentine drive system with matched components rather than replacing only the belt. That approach helps address wear in the tensioner and idler pulley at the same time, which is important on high-mileage front accessory drives where component wear can affect belt tracking and service life. Gates 90K-38139C cross-references DBK061031A for the same application.

Fits 1996 Ford Windstar, N/A. Fits 1997 Ford Windstar, N/A. This part number is also identified as 90K-38139C for catalog and service lookup.

Common Repair Reasons

• Squealing or chirping from the serpentine belt drive
• Visible belt wear, glazing, or cracking
• Weak or inconsistent belt tension
• Idler pulley noise or rough rotation
• Tensioner wear affecting accessory drive performance

Installation Notes

Use the vehicle notes to confirm the correct belt outside circumference before installation. For the listed Ford Windstar applications, the notes specify a 103 1/4 in. belt outside circumference. Inspect the belt routing, pulley alignment, and accessory drive components before final assembly. Follow the included installation instructions and tech tips for accurate fitment and setup.

Quality Assurance

Gates supplies this kit as a complete serpentine service solution with OE-equivalent components and application-specific hardware guidance in the package materials. The goal is to help restore the accessory belt drive system with parts matched to the vehicle application.
