Gates Serpentine Belt P/N:K100563HD

Keep the cooling fan and alternator spinning with the Gates Serpentine Belt K100563HD, a single multi-ribbed belt that transfers power from the engine's crankshaft to the fan-and-alternator drive. It's a direct-fit replacement for a range of heavy-duty trucks, including the 2021-2022 and 2024-2025 Freightliner Cascadia, the 2011-2016 Hino 238, 258, 268 and 338, and the 1990-1994 International 8200 and 8300 — see the Buyer's Guide tab for the full list of listed applications.

• Fan-and-alternator drive: routes over the accessory pulleys to turn the cooling fan and alternator from a single belt.
• One-belt serpentine design: loops through the accessory drive so a worn or cracked original can be swapped as one continuous belt.
• Signs it may need replacing: belt squeal or chirp, visible cracking, glazing, or fraying along the ribs.
• Application-matched fit: a direct-fit replacement for the listed applications.

A serpentine belt wears gradually with heat, tension, and mileage. If a worn, glazed, or cracked belt is the cause of squealing or an accessory that isn't turning, replacing it with this belt helps restore the belt drive. Inspect the tensioner and pulleys at the same time so the new belt runs true.
