Agility Autoparts HVAC Heater Core P/N:9010171
Bring warm air back to the cabin with the Agility Auto Parts HVAC Heater Core 9010790, a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2017-2025 Chevrolet Malibu, 2017-2019 Buick LaCrosse and 2019-2025 Cadillac XT4; see the Buyer's Guide tab for the full list. Mounted in the front HVAC module, this core is a compact coolant-to-air heat exchanger: hot engine coolant circulates through its aluminum tubes while the blower pushes air across the fins to warm the cabin and help defog the glass.
Signs this core may need replacing include weak or no cabin heat, a sweet coolant odor inside the car, fog on the inside of the windshield, or coolant seeping under the dash. If a failed heater core is the cause, this unit replaces it. Made in China.
