Keep the fan, alternator, and other engine accessories turning while quieting belt squeal with the Gates Serpentine Belt K081023. It routes over the accessory-drive pulleys as a direct-fit replacement for the 2006-2008 Kenworth T800, 2005 Peterbilt 357, 2005 Peterbilt 362, 2004-2006 Peterbilt 378, and 2004-2007 Peterbilt 379.

A single serpentine belt loops over the crankshaft and accessory pulleys to transfer power from the engine to the driven components. On these applications it drives the fan and alternator, and depending on the truck it also turns the air conditioning and power steering.

  • Multi-accessory drive: one belt routes over the pulleys to power the fan and alternator, and on equipped applications the air conditioning and power steering.
  • Wraps the pulley system: installs by routing over the existing pulleys and tensioner — no bolt-on hardware.
  • Signs it may need replacing: belt squeal, visible cracks, glazing, fraying, or chunks missing from the ribs.

If a worn or noisy belt is the cause of your squeal or lost accessory drive, this replaces it. Manufacturer part number K081023.
