Front HVAC Housing
HOUSING-HVAC ASSEMBLY
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system Refrigerant Oil Level . 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: 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.
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 Refrigerant Oil Level .
NOTE: Replacement of the refrigerant line seals is required anytime a refrigerant line is disconnected. Failure to replace the rubber and metal seals could result in a refrigerant system leak.
NOTE: LHD model shown in illustrations. RHD model similar.
