Disassembly And Assembly: Assembly

CAUTION:

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.

NOTE:

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 STANDARD PROCEDURE - REFRIGERANT OIL LEVEL .

NOTE:

If the rear 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.

NOTE:

Replacement of the refrigerant line O-ring seals is required anytime the A/C expansion valve is removed from the A/C evaporator. Failure to replace the rubber O-ring seals may result in a refrigerant system leak.
