Discharge Line

INSTALLATION

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: 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 systemRefrigerant Oil Level.

NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals 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 condenser and compressor ports.
3. Lubricate new rubber O-ring seals with clean refrigerant oil and install them 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 (7).
5. Install the bolt (2) that secures the A/C discharge line to the A/C compressor. Tighten the bolt to 23 Nm (17 ft. lbs.).




6. Connect the A/C discharge line (4) to the A/C condenser (7).
7. Install the bolt (5) that secures the A/C discharge line to the A/C condenser. Tighten the bolt to 18 Nm (13 ft. lbs.).




8. Install the bolt (2) that secures the A/C discharge (1) to the left frame rail (6). Tighten the bolt securely.
9. If removed, install the A/C pressure transducer (3) onto the A/C discharge line using a new O-ring seal. Tighten the transducer securely.
10. Connect the wire harness connector (5) to the A/C pressure transducer.
11. Install the air intake ducts to the front of the air cleaner assembly .
12. Reconnect the negative battery cable.
13. Evacuate the refrigerant system Refrigerant System Evacuate.
14. Adjust the refrigerant oil level Refrigerant Oil Level.
15. Charge the refrigerant systemRefrigerant System Charge.
