Removal And Installation: 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, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. Refer to OIL, REFRIGERANT, STANDARD PROCEDURE .
If only the A/C evaporator is being replaced, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrigerant system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
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.
- Position the rear A/C evaporator (1) into the inboard half of the HVACR housing. Make sure the blend-air door and the mode-air door are properly installed to the pivots located in the inboard half of the HVACR housing.
- Assemble the HVACR housing. Refer to HOUSING, A/C AND HEATER, REAR, DISASSEMBLY AND ASSEMBLY .
