Detailed Description

Gates 90K-38133A is an Accessory Belt Drive Kit from the Gates Accessory Belt Drive Kit line, created to service the full serpentine drive rather than replacing only the belt. By addressing the belt, tensioner, and idler pulley together, this kit helps restore proper accessory drive operation on Ford Expedition and Lincoln Navigator models listed in the fitment data. This part cross-references Litens LV999266A for the same application.

The kit uses an OE-equivalent belt with a 98.64-inch outside circumference and 28 mm top width, making it a direct-spec service option for vehicles that require K080981, 38133, and 38022 components. Search terms such as Ford Expedition serpentine belt kit, Lincoln Navigator accessory drive kit, and 1997-2001 Ford Expedition belt tensioner idler kit all point to this application.

What It Helps Address

• Squealing or chirping from a worn serpentine belt
• Belt tracking issues caused by a weak tensioner
• Noise from a worn idler pulley
• Repeated belt replacement when related drive components are left in service
• Accessory drive performance problems on Ford Expedition and Lincoln Navigator models
