Product Details

Gates built the 9570HD for heavy-duty drives that see frequent load changes and extended service intervals. The EPDM compound and distinct green overcord are part of the FleetRunner heavy-duty belt line, which is engineered for longer life in demanding accessory drive systems. The notched profile helps the belt track smoothly around pulleys used on fan and alternator or air conditioning drives.

This part cross-references Dayco 89573 and Continental 17570 for the same application. The Gates 9570HD also appears in interchange listings for a wide range of OE and aftermarket references, making it a practical replacement choice when matching the original belt size and section is critical.

Common Problems This Belt Can Address

• Squealing from a worn or glazed accessory drive belt
• Cracking, fraying, or visible belt wear
