The Gates molded heater-to-pipe coolant hose for 1997–2002 Ford Expedition 5.4L V8 connects the heater circuit to the pipework and functions as a direct replacement of that molded section. It preserves coolant flow through the heater lines and helps restore proper heating and engine temperature regulation as part of routine cooling system maintenance.
