Dayco HVAC Heater Hose P/N:87959
Dayco 72079 heater hose for the 2000-2004 Ford Focus carries engine coolant between the pipe and the thermostat. This Dayco heater hose installs at the pipe-to-thermostat position, and some catalogs list it as an HVAC heater hose.
Coolant drips or stains at the hose, a sweet smell, low coolant, or a hose that is cracked, soft or swollen can mean the heater hose is failing. Before you replace it, rule out a loose clamp or a leak at the thermostat housing, since either can leave coolant on the engine.
It fits the 2000-2002 Ford Focus and the 2003-2004 Ford Focus L4-2.0L. Each Focus takes one, on the run from the pipe to the thermostat.
