Gates 7318 Accessory Drive Belt - Air Pump or Fan To Air Pump

Gates 7318 High Capacity V-Belt Overview

The Gates 7318 High Capacity V-Belt is a replacement accessory drive belt for demanding engine drive systems. Built with EPDM belt material and polyester cord reinforcement, it is made for stable operation as engine temperatures rise and belt loads increase.

This Gates High Capacity V-Belt (Standard) uses a variable notched design to tighten on the drive as it heats up, helping reduce slippage and belt noise while maintaining consistent performance. It is a direct-fit option for select Ford, Lincoln, and Mercury applications, including Ford Ranger, Bronco, F-Series trucks, Thunderbird, and related air pump and fan-to-air-pump positions.

Product Details

Gates 7318 is built for accessory drive systems that need a dependable V-belt with controlled tension behavior under heat. The notched profile is engineered to tighten as operating temperature increases, which helps maintain grip on the pulley system and supports quieter operation. For buyers searching for a Ford Ranger accessory drive belt, Ford F-150 air pump belt, or a replacement V-belt for classic Ford and Mercury engine drives, this part number provides a focused fitment match.

This part cross-references Dayco 09320 for the same application.

• Belt slippage in heated engine compartments
• Squealing or noise from worn accessory drive belts
• Loss of drive to air pump or fan-to-air-pump accessories
