Cabin heat and defrost start at the heater core. The Agility Auto Parts Heater Core 9010066 is built to pass engine coolant heat into the air your blower moves through the HVAC system. It fits many vehicles, among them the 1971-1985 Chevrolet Impala, 1971-1975 Chevrolet Bel Air and 1971-1990 Chevrolet Caprice, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
Hot coolant from the engine circulates through the core while air passes across its fins, carrying heat into the passenger compartment. Shopping for a 1971-1990 Chevrolet Caprice heater core or one for another listed model? Signs this HVAC heater core may need replacing include weak or no cabin heat, a sweet coolant smell inside the car, a greasy film fogging the windshield, damp carpet, or unexplained coolant loss. Diagnose the cause before replacing it, because other cooling or HVAC faults can produce similar signs.

What does a heater core do?
It works like a small radiator inside the HVAC housing. Hot engine coolant flows through its tubes and fins, and air blown across it carries that heat into the cabin for heating and defrost.
How is the Agility 9010066 quality checked?
Agility heaters are engineered and manufactured under ISO TS16949 quality systems, are 100% leak tested, and are fitment checked in the actual vehicle's HVAC heater module.
Is the heater core difficult to install?
It is designed for a drop-in fit, but the job involves the HVAC heater module and the cooling system. Follow the vehicle service information, and refill the coolant as directed.
What are signs of a failing heater core?
Weak or no cabin heat, a sweet coolant smell, a greasy film on the windshield, damp carpet or unexplained coolant loss may indicate a failing core. Diagnose the cause first, because other faults can look similar.
