The Gates molded heater hose for 1999–2003 Ford Super Duty with the V‑8 7.3L diesel engine connects the reservoir to the radiator. This replacement restores the intended coolant pathway, replacing cracked or leaking hoses common in heavy‑duty use. Verify the 7.3L diesel application and reservoir‑to‑radiator routing to ensure the molded hose matches the vehicle's original cooling‑system configuration.
