A/C EVAPORATOR CORE

NOTE: If an evaporator core leak is suspected, the evaporator core must be vacuum leak tested before it is removed.

The A/C evaporator core is a plate/fin type used to remove heat and humidity from the blower motor airflow before it is delivered to the passenger compartment when A/C operation is selected.
- A mixture of refrigerant and oil enters the bottom of the A/C evaporator core through the A/C evaporator core inlet tube and then moves out of the A/C evaporator core through the A/C evaporator core outlet tube.
- All airflow from the blower motor passes through the evaporator core before reaching the heater core.
