Dayco 87756 heater hose for the 1997-2003 Ford F-150 V8 4.6L or 5.4L and other vehicles carries engine coolant through the heater circuit. Also listed as an HVAC heater hose, it is needed once per vehicle.
Coolant drips, a sweet coolant smell or a cabin that stays cold can mean a heater hose is wearing out. Before you replace the hose, rule out the heater core, the coolant level (checked only with the engine cool) and the thermostat, since each of those can also leave the cabin cold.
The 1997-2003 Ford Expedition V8 4.6L or 5.4L and the 1997-1999 Ford F-250 V8 4.6L or 5.4L are among the vehicles this heater hose fits, along with more Ford and Lincoln models. If your vehicle is not named here, look up its year, model and engine in the "Vehicles it fits" section.
