The Gates heater hose is a molded replacement that connects the heater to Pipe‑1 on 1997–2003 Ford F‑Series trucks with the 5.4L V8, restoring the intended coolant routing. The hose's molded design follows the original heater-to-pipe geometry for that engine application, providing a straightforward, application-specific option to maintain proper coolant flow between the heater and pipe connection.
