Description

Keep the fan, alternator, water pump, and air conditioning spinning with the Gates Serpentine Belt K120842. This single multi-ribbed belt loops over the engine's accessory pulleys to transfer power from the crankshaft, and it drops in as a direct-fit replacement across a range of heavy-duty trucks — including the 2021-2025 Freightliner Cascadia, 2020 International LT and LT625, 2019 International ProStar, and numerous Volvo VNL, VNM, and VT models.

Accessory coverage: routes the fan, alternator, water pump, and air conditioning drive.
Direct-fit replacement: a direct-fit belt for the listed applications.
Signs of wear: squealing, chirping, visible cracking, glazing, fraying, or missing ribs are common signs a serpentine belt may need replacing.

If a worn or cracked belt is the cause of your accessory-drive noise or slipping, this belt replaces it. Inspect the tensioner and pulleys at the same time so the new belt seats and tracks correctly. See the Buyer's Guide tab for the complete list of covered years, makes, and models.
