It is listed for 2014-2018 Chevrolet Silverado 1500, 2014-2018 Chevrolet Silverado 2500, 2015-2020 Cadillac Escalade, 2015-2020 Cadillac Escalade ESV, 2015-2020 Chevrolet Tahoe, 2015-2019 GMC Yukon, 2015-2019 GMC Yukon XL, 2015-2018 GMC Sierra, 2014-2018 GMC Sierra 1500, 2018 Chevrolet Cheyenne, and 2019 GMC Sierra 1500 Limited.

Common Issues It Can Help Address

  • Belt squeal caused by weak or inconsistent tension
  • Visible belt flutter or vibration at idle
  • Reduced accessory drive stability on GM V8 platforms
  • Noise from a worn tensioner pulley or spring mechanism
  • Uneven belt wear from improper belt tracking

Installation Notes and Tips

Verify the vehicle year, make, and model against the listed fitment before ordering. Inspect the serpentine belt, pulleys, and related accessory drive components during replacement, since worn parts can shorten the service life of the new tensioner. Confirm the mounting location and belt routing match the original setup on your Silverado 1500, Sierra 1500, Tahoe, Yukon, or Escalade application.
