Help warm the rear cabin back up with the Agility Auto Parts HVAC Heater Core 9010255 — a direct-fit rear heater core that replaces a worn or leaking 1993-1999 Nissan Quest heater core and the matching unit in the 1993-2002 Mercury Villager. It routes engine coolant through its aluminum core so the HVAC blower can transfer that heat into the rear passenger area.
The core measures 6.500 in wide, 5.875 in tall and 2.000 in deep, with 0.625 in inlet and outlet pipes. If your rear heater blows cool, you notice a sweet coolant smell, fogged windows, or unexplained coolant loss, a failed heater core may be the cause — this unit replaces it. See the Buyer's Guide tab to confirm your year and application. Country of origin: China.
