Gates Serpentine Belt P/N:K120463

Silence belt squeal and keep the engine's fan and accessories turning with the Gates Serpentine Belt K120463. It installs as a direct-fit replacement for the 2014 Peterbilt 579, routing over the fan and accessory drive pulleys to transfer power from the crankshaft to the belt-driven components.

• Fan-drive belt: Cataloged for the FAN position, this single multi-ribbed belt loops over the drive pulleys to keep the accessory system spinning.
• One-belt drive: A serpentine belt drives multiple components from a single routed loop, so a worn belt affects everything on that path.
• Signs it may need replacing: Squealing on start-up, visible cracking or glazing, missing chunks along the ribs, or fraying edges are common signals that a serpentine belt is due for service.
• Direct-fit replacement for the 2014 Peterbilt 579; it routes over the existing accessory pulleys.

If a worn or damaged belt is behind squealing or a loss of accessory drive, this replaces it. Inspect the tensioner and pulleys during installation, since they share the same drive path.
