CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Heating and Air Conditioning/Service
and Repair/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, see the Refrigerant Oil Capacities chart to determine how much oil should be added
to the refrigerant system See: Heating and Air Conditioning/Service and Repair/Refrigerant Oil Capacity .
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. Failure to replace
the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
NOTE: Illustration shown with lower radiator hose removed for clarity.
1. If removed, install the A/C pressure transducer onto the A/C discharge line (4) See: Heating and Air Conditioning/Refrigerant Pressure Sensor /
Switch/Service and Repair/A/C Pressure Transducer - Installation.
2. Remove the tape or plugs from the discharge line fittings and the compressor and jumper line ports.
3. Lubricate new O-ring seals with clean refrigerant oil and install them and new gaskets onto the discharge line fittings. Use only the specified
O-ring seals as they are made of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C
compressor in the vehicle.
4. Connect the A/C discharge line to the A/C compressor (2).

6. Install the turbocharger outlet hose.
7. Connect the A/C discharge line (2) to the condenser jumper line tapping block (4) and install the nut (3). Tighten the nut to 23 Nm (17 ft. lbs.).
8. Connect the wire harness connector to the A/C pressure transducer (1).
9. Reconnect the negative battery cable.
10. Install the air filter housing.
11. Evacuate the refrigerant system See: Heating and Air Conditioning/Service and Repair/Refrigerant System Evacuate.
12. Adjust the refrigerant oil level See: Heating and Air Conditioning/Service and Repair/Refrigerant Oil Capacity.
13. Charge the refrigerant system See: Heating and Air Conditioning/Service and Repair/Refrigerant System Charge.
