Product Details

Gates engineered this Micro-V belt to match OE dimensions and materials, helping maintain proper drive alignment and accessory operation in the engine belt system. The K140429 uses a K cross section and 14 ribs, making it a fitment-specific serpentine belt for applications that call for this exact profile. If you are searching for a Gates serpentine belt for a Ford F-150, Mustang, or similar vehicle application that uses this size, K140429 is the part number to verify against the original belt.

This part cross-references Dayco 5140430 for the same application.

What It Helps Address

  • Squealing or chirping from a worn serpentine belt
  • Cracking, glazing, or rib wear on the accessory drive belt
  • Loss of proper drive to alternator, power steering, or other belt-driven accessories
  • Belt length or profile mismatch during replacement
  • Reduced belt stability caused by age, heat, and mileage

Installation Notes and Tips

Verify the original belt length, rib count, and cross section before installation. Compare the removed belt or OEM specification to the K140429 dimensions: 14 ribs, 42.98-inch effective length, and 1.927-inch top width. Inspect pulleys, tensioner operation, and belt routing before fitting the new belt to help prevent premature wear.

For vehicle-specific searches, confirm the application against your Ford F-150, Mustang, or other make/model using the same belt profile and dimensions. The part number K140429 should match the OE specification for the intended accessory drive system.

Quality Assurance

Gates positions the Premium OE Micro-V Belt line as an OE-style replacement program, using matched construction and materials to support original-equipment fit and performance standards. The EPDM belt compound and polyester cord are selected for durability in demanding underhood conditions.
