Evaporator Core: Service and Repair
Front A/C Evaporator - Installation
INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Specifications/Capacity
Specifications/Refrigerant Oil Capacity . Failure to properly adjust the refrigerant oil level will prevent the A/C system from
operating as designed and can cause serious A/C compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be
added to the refrigerant system See: Specifications/Capacity Specifications/Refrigerant Oil Capacity .
NOTE: If only the A/C evaporator is being replaced, add 60 milliliters (2 fluid ounces) of refrigerant oil to the refrigerant system. Use only
refrigerant oil of the type recommended for the A/C compressor in the vehicle.
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line or expansion valve is disconnected.
Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
1. Install the A/C evaporator (1) into the lower half of the HVAC housing (2). Make sure that the evaporator drain is clean and unrestricted and that
the evaporator insulator (3) is properly installed.
2. Install the probe for the evaporator temperature sensor into the fins of the A/C evaporator See: Evaporator Temperature Sensor / Switch/Service
and Repair/Front Evaporator Temperature Sensor - Installation
3. Assemble the HVAC housing See: Housing Assembly HVAC/Service and Repair/Overhaul/Assembly/Front HVAC Housing.
4. Install the HVAC housing See: Housing Assembly HVAC/Service and Repair/Removal and Replacement/Front HVAC Housing Installation.
5. If the A/C evaporator is being replaced, add 60 milliliters (2 fluid ounces) of refrigerant oil to the refrigerant system. When replacing multiple A/C
system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system See:
Specifications/Capacity Specifications/Refrigerant Oil Capacity. Use only refrigerant oil of the type recommended for the A/C compressor in the
vehicle.
