Keep coolant flowing to your heater core with the Dayco HVAC Heater Hose 87813. This heater hose is a direct-fit replacement for the 2007-2012 Mazda CX-7 and the 1999-2002 Mercury Cougar, routing engine coolant along the heater circuit so warm coolant can reach the cabin heat exchanger. It is cataloged for the HEATER TO PIPE, HEATER OUTLET position.
Signs this hose may need replacing include coolant seepage or drips near the heater connections, a soft or bulging hose, or low coolant level. If a failed heater hose is the cause of your leak or lost cabin heat, this replaces it; diagnose the source of any coolant loss before replacing parts.
