It has a 2.5‑inch inner diameter and an approximately 8.875‑inch centerline length, connecting the radiator to the engine on many Class 8 trucks. Replace your original hose when it becomes soft, swollen, or cracked to prevent coolant leaks and overheating. The silicone material offers longer life and better heat resistance than conventional rubber hoses.
