Accessory Drive Belt for 1987-1996 Peterbilt 379 truck & More - Gates 9660HD

Gates 9660HD belt drive components for the 1987-1996 Peterbilt 379 truck 10.5L and other vehicles and equipment come as a single-strand FleetRunner Heavy-Duty V-belt built for heavy-duty drives.

• Patented EPDM construction with a distinct green overcord, built for more durability and longer life on heavy-duty drives
• Patented material gives peak performance at extremely prolonged operating temperatures
• Heavy-duty construction resists cracking, wear, oil and heat
• A special compound adds stability, load carrying capacity and belt life
• Unique undercord notch pattern gives more flexibility on smaller diameter pulleys
• Meets RMA oil and heat resistant standards and static conductivity requirements

A cracked, frayed or oil-soaked belt, or a chirp or squeal in normal driving, can mean the belt is worn. A squeal alone does not prove the belt is the problem, since a worn tensioner can make that noise too.

As a heavy-duty V-belt, it also fits the 1987-1996 Peterbilt 357 truck 10.5L and the 1987-1996 Peterbilt 375 truck 10.5L, and each of those takes two. The quantity varies by engine across the other vehicles and equipment, so open the "Vehicles it fits" section and check your exact model and engine.
