The Gates heater hose is a molded replacement that connects the heater to the intake manifold on 1997–2003 Ford F‑Series trucks with the 5.4L V8, restoring correct heater circuit routing. Its molded profile corresponds to the heater-to-intake manifold path for that application, offering an application-specific option to maintain proper coolant flow between the heater and the intake manifold connection for the listed model years.
