Evaporator Core: Service and Repair
Evaporator Core
EVAPORATOR CORE
Removal and Installation
NOTE:
-
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 receiver/drier cartridge is not required when repairing the air conditioning system except when there is physical evidence of
contamination from a failed A/C compressor or damage to the receiver/drier cartridge.
-
A new evaporator core seal is supplied as a kit with the evaporator core service part. Failure to install this seal, or failure to install it correctly, will
result in air bypassing the evaporator core and loss of cooling efficiency.
1. Remove the plenum chamber.
2. Remove 2 heater core quick disconnect fitting clips and the dash panel seal.
