Dayco Engine Coolant Bypass Hose,Engine Coolant Hose,HVAC Heater Hose P/N:86815
Dayco 87814 heater hose for the 2013-2015 Acura RDX and other vehicles carries engine coolant between the heater and the thermostat.
A worn HVAC heater hose can show up as coolant drips, a soft or swollen spot, or a coolant level that keeps dropping. With the engine off and cool, look along the hose and at both ends for wetness. If the hose is the source of the loss, this one replaces it, so find where the coolant is going before you order.
This heater hose fits the 2013-2015 Acura RDX, the 2001-2003 Mazda Protege 4-cylinder 2.0L and the 2002-2003 Mazda PROTEGE5. Each of them takes one hose at the heater inlet.
