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.

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 (2) onto the A/C discharge line (3). 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 line fitting and the condenser port.

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. Reach down through the opening between the radiator and the front fascia and connect the A/C discharge line to the A/C condenser (4).

6. Install the nut (5) that secures the A/C discharge line to the A/C condenser. Tighten the nut to 5 Nm (44 in. lbs.).

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

8. Install the upper radiator closure panel.




9. Raise and support the vehicle.

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

11. 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.

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

13. 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.).

14. Install the splash shield onto the right side frame rail.

15. Lower the vehicle.

16. 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.

17. Evacuate the refrigerant system.

18. Adjust the refrigerant oil level.

19. Charge the refrigerant system.
