Gates 9580 Accessory Drive Belt

Gates 9580 High Capacity V-Belt Overview

The Gates 9580 is a High Capacity V-Belt (Standard) built for accessory drive systems that see steady heat and load. This Gates XL V-belt uses a notched construction and EPDM belt material to help maintain grip, reduce slippage, and lower operating noise as engine temperatures rise.

Compatible With Ford E-350 Econoline, Ford F-250, Ford F-350, and other listed applications, this belt is sized for accessory drive service where consistent fan, alternator, power steering, or air conditioning performance matters. The 9580 part number is also a useful reference when cross-shopping replacement belts for older Ford and Cadillac applications.

Product Details

Gates built the 9580 for engines that place continuous demand on the accessory drive system. The variable notched profile is engineered to tighten as heat builds, which helps the belt maintain contact on the pulleys and supports smoother operation under load. That makes this belt a practical choice for older Ford truck and van platforms, including Ford E-250 Econoline Club Wagon, Ford E-350 Econoline, and Ford F-150 applications listed in the fitment data.

This part cross-references Gates 9580HD and 70560 for the same application. It also appears in interchange listings for several aftermarket and OE-style replacement numbers, making it easier to verify the correct belt when servicing Ford E-350 Econoline, Ford F-250, or Ford F-350 accessory drive systems.

What This Belt Helps Address

• Squealing from a worn or glazed accessory drive belt
• Belt slip under heat and engine load
• Reduced alternator, fan, power steering, or A/C drive consistency
• Cracking, fraying, or visible wear on the existing V-belt
• Noisy operation from an aging belt in the accessory drive system

Installation Notes and Tips

Verify the belt length, top width, and section designation against the existing belt and vehicle application before installation. Confirm the listed position and configuration, since the fitment data includes fan and alternator, fan and power steering, power steering and air conditioning, air conditioning, and fan and air conditioning applications across different vehicles.

For best results, inspect pulleys and belt alignment before installing the new belt. A worn pulley, misalignment, or contamination on the drive surfaces can shorten belt life and affect performance. This belt is listed for specific Ford, Cadillac, Mercedes-Benz, and Mercury applications, so match the vehicle, year, and accessory drive layout carefully.

Quality Assurance

Gates is known for producing replacement drive components for automotive accessory systems, and the 9580 follows that focus with EPDM construction, polyester reinforcement, and a notched profile for heat-related belt loading. The product information provided does not include a warranty statement.
