The Gates Micro‑V heavy‑duty V‑ribbed belt for 2002–2004 International/Navistar 4300 diesel is built for fan‑to‑A/C accessory routing where a more robust belt is needed. Specified as a heavy‑duty serpentine replacement, it preserves correct rib engagement and tensioner compatibility to handle higher load demands in that chassis application without altering factory routing.
