Evaporator Core: Description and Operation
Main Climate Control
NOTE:
-
The evaporator core is not separately serviceable, it is serviced only with the evaporator core housing assembly.
-
If an evaporator core leak is suspected, the evaporator core must be vacuum leak tested before it is removed from the vehicle.
-
Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of
system contamination from a failed A/C compressor or damage to the suction accumulator.
The evaporator core is the plate/fin type with a unique refrigerant flow path.
-
A mixture of refrigerant and oil enters the bottom of the evaporator core through the evaporator core inlet tube, continues over to the remaining
five plate/fin sections, and then moves out of the evaporator core through the evaporator core outlet tube.
-
This S-pass flow pattern accelerates the flow of refrigerant and oil through the evaporator core.
