Dayco HVAC Heater Hose P/N:87959
Dayco 86803 heater hose for the 1998-1999 Nissan Sentra 4-cylinder 2.0L and other vehicles is a coolant hose in the heater circuit. This Dayco heater hose, also called an HVAC heater hose, carries hot coolant from the engine so the heater can warm the cabin.
A cracked or swollen hose, a coolant leak or a falling coolant level can mean a heater hose needs replacing. A loose clamp, a weak water pump or a leaking heater core can show up the same way, so find the source of the problem before you buy.
The 1998-1999 Nissan Sentra 4-cylinder 2.0L, the 1992-1995 Honda Civic 4-cylinder 1.5L or 1.6L and the 1999-2003 Chevrolet Tracker 4-cylinder 2.0L are among the vehicles this hose fits. The 1999-2003 Chevrolet Tracker 4-cylinder 2.0L takes one. If your car isn't named here, look up its year, make and model in the "Vehicles it fits" section.
