Help keep warm air flowing into the cabin with the Agility Auto Parts Heater Core, part number 9010110, which passes hot engine coolant through its tubes and fins so the blower can carry that heat inside. It fits many vehicles, among them the 1978-1983 Jeep Cherokee, 1984-1991 Jeep Grand Wagoneer and 1978-1988 Jeep J10. See the Buyer's Guide tab for the full list.
Agility builds its heaters with enhanced design features, including the latest fin and tube technology, for increased thermal performance and resistance to corrosion. Each unit is fitment checked in the actual vehicle's HVAC heater module, so it is ready to install right out of the box for a drop-in fit. If a leaking or clogged heater core is the cause of weak cabin heat or a coolant odor inside, this core replaces it.
The listed applications use one heater core. Country of origin: United States.
