What This Kit Helps Address

  • Squealing or chirping from a worn serpentine belt
  • Loss of belt tension from a fatigued tensioner
  • Noise from a worn idler pulley bearing
  • Uneven belt wear caused by aging front-end drive components
  • Repeat accessory drive service on Ford Bronco and Ford truck applications

Installation Notes and Tips

Verify the vehicle uses factory air conditioning and a visible spring design before ordering. Confirm belt routing and component numbers against the existing accessory drive layout, especially on 1990-1992 Ford Bronco, F-150, F-250, and F-350 models. Use the included installation instructions and tech tips to support accurate installation and proper belt alignment.

Quality Assurance

Gates supplies this kit as a complete serpentine drive service package with OE-equivalent component specifications. The matched belt, tensioner, and idler pulley are selected to help restore the accessory belt drive system as a unit rather than replacing only the belt.
