Gates Serpentine Belt P/N:K100495

Keep the accessory drive turning quietly with the Gates Serpentine Belt K100495, a direct-fit replacement belt for the 1981-1982 GMC Astro. A single serpentine belt routes over the engine's pulleys to transfer power from the crankshaft to the belt-driven accessories, and this Gates belt is cataloged for the fan-drive position on those applications.

• Purpose: Loops over the drive and accessory pulleys to spin engine accessories from crankshaft rotation.
• Fan position: Cataloged for the FAN drive on the listed application.
• Direct-fit application: A direct-fit replacement for the 1981-1982 GMC Astro.
• Signs it may need replacing: Belt squeal or chirp, visible cracking, glazing, or fraying along the belt.

A worn or cracked belt can slip and let accessory speed drop; if a failed belt is the cause, this replaces it. Inspect the tensioner and pulleys during installation. Fitment: 1981-1982 GMC Astro. Manufacturer part number K100495.
