Evaporator, A/C: Installation
Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. 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.
When replacing multiple A/C system components, see the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. Refer to OIL, REFRIGERANT, STANDARD PROCEDURE .
If 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.
- Install the foam seal (2), tapping block and A/C expansion valve onto the A/C evaporator (1). Refer to VALVE, A/C EXPANSION, INSTALLATION .
- Install the A/C evaporator into the lower half of the HVAC housing (3). Make sure that the evaporator drain within the HVAC housing is clean and unrestricted and that the insulator around the A/C evaporator is properly installed.
- Assemble the HVAC housing. Refer to HOUSING, HVAC, INSTALLATION .NOTE:
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, see the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. Refer to OIL, REFRIGERANT, STANDARD PROCEDURE . Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
- Install the HVAC housing assembly. Refer to HOUSING, HVAC, INSTALLATION .
