A/C Discharge Line - Installation

INSTALLATION

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, refer to 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 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. If removed, install the A/C pressure transducer (6) onto the A/C discharge line (2). Tighten the A/C pressure transducer securely.

2. Position the A/C discharge line into the engine compartment.

3. Remove the tape or plugs from the discharge and jumper line fittings.

4. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it and a new gasket onto the discharge line fitting. Use only the specified O-ring as it is 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.

5. Connect the A/C discharge line to the jumper line (4).

6. Install the nut (3) that secures the A/C discharge line to the jumper line. Tighten the nut to 18 Nm (13 ft. lbs.).

7. Connect the wire harness connector (1) to the A/C pressure transducer.





8. Raise and support the vehicle.

9. Remove the tape or plugs from the discharge line fitting and the compressor port.

10. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it and a new gasket onto the discharge line fitting. Use only the specified O-ring as it is 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.

11. Connect the A/C discharge line (2) to the A/C compressor (3).

12. Install the nut (1) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 20 Nm (15 ft. lbs.).

13. Install the splash shield onto the right side frame rail Splash Shield - Installation.

14. Lower the vehicle.

15. Reconnect the negative battery cable.

CAUTION:
Do NOT run the engine with a vacuum pump in operation or with a vacuum present within the A/C system. Failure to follow this caution will result in serious A/C compressor damage.

16. Evacuate the refrigerant system Refrigerant System Evacuate.

17. Adjust the refrigerant oil level Refrigerant Oil Level.

18. Charge the refrigerant system Refrigerant System Charge.
