Evaporator Core

NOTE: Application of an A/C deodorizer or cooling coil coating product to the evaporator core is not approved by Ford Motor Company for this vehicle. Application of an A/C deodorizer or cooling coil coating may interfere with the anti-microbial coating that is applied to the evaporator core at the factory, or the efficiency of the evaporator core.

NOTE: The evaporator core is available only as part of the evaporator core housing assembly.

The evaporator core is an aluminum plate/fin type and is located in the heater core and evaporator core housing. A mixture of liquid refrigerant and oil enters the bottom of the evaporator core through the evaporator core inlet tube and continues out of the evaporator core through the evaporator core outlet tube as a vapor. During A/C compressor operation, airflow from the blower motor is cooled and dehumidified as it flows through the evaporator core fins.
