INSTALLATION
3.0L ENGINE
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT OIL - STANDARD PROCEDURE - 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: 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 24 - HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT OIL - STANDARD PROCEDURE - REFRIGERANT OIL LEVEL).
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
1. Position the A/C discharge line (1) into the engine compartment.
2. Remove the tape or plugs from the opened discharge line fittings and the compressor and condenser ports.
3. Lubricate new dual-plane seals with clean refrigerant oil and install them onto the discharge line fittings. Use only the specified 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. Install the A/C discharge line onto the A/C compressor (4).
5. Install the nut (6) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 20 N·m (15 ft. lbs.).
6. Install the A/C discharge line (4) into the retaining bracket (2) and to the A/C condenser (4).
7. Install the nut (5) that secures the A/C discharge line to the A/C condenser. Tighten the nut to 20 N·m (15 ft. lbs.).
8. If removed, install the A/C pressure transducer (6) onto the A/C discharge line. Tighten the A/C pressure transducer securely.
9. Connect the wire harness connector (7) to the A/C pressure transducer.
10. Install the air cleaner housing, air intake tube and the resonator (refer to 9 - ENGINE/AIR INTAKE SYSTEM/HOUSING-AIR CLEANER - INSTALLATION).
11. Install the grille (refer to 23 - BODY/EXTERIOR/GRILLE - INSTALLATION).
12. Reconnect the negative battery cable.
13. Evacuate the refrigerant system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM EVACUATE).
14. Adjust the refrigerant oil level (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT OIL - STANDARD PROCEDURE - REFRIGERANT OIL LEVEL).
15. Charge the refrigerant system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM CHARGE).
