Product Details

Gates engineered the FleetRunner Heavy Duty Micro-V Belt line for fleet vehicles and other high-demand drivetrains where belt stability matters. The EPDM compound and green overcord help the belt maintain flexibility and consistent tracking under accessory loads, while the polyester cord supports tension retention and fit consistency. If you are replacing a worn serpentine belt on a Ford F-150 or Lincoln Mark LT, K060640HD provides the dimensions and rib count needed for the specified accessory drive applications.

This part cross-references Continental 4060640 and Dayco 5060640 for the same application.

Common Problems This Belt Can Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of belt tracking on alternator and water pump drives
• Reduced belt stability under heavy accessory load
• Service downtime caused by premature belt replacement

Installation Notes and Tips

Verify rib count, belt length, and section designation before installation. Confirm routing against the vehicle’s belt diagram and inspect pulleys, tensioners, and idlers for wear before fitting the new belt. For Ford F-150 and Lincoln Mark LT applications, confirm the accessory drive configuration matches the listed alternator and water pump setup before ordering K060640HD.
