The Gates heater hose is a molded replacement that connects the heater to the water pump on 1999–2003 Ford Super Duty trucks with the 7.3L diesel V8, restoring the cooling circuit's routing. The molded shape corresponds to the heater-to-water-pump path for that application, providing an application-specific option to ensure proper coolant movement between the heater connection and the water pump.
