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. Position the A/C suction line (2) into the engine compartment.

2. Install the A/C suction line into the liquid line tapping block (4).

3. Install the plastic retainer (1) that secures the A/C suction line to the liquid line tapping block.

4. Remove the tape or plugs from the suction and liquid line fittings and the A/C expansion valve (5).

5. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and a new gasket onto the suction and liquid line fittings. Use only the specified O-rings 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.

6. Connect the A/C suction line and A/C liquid line to the A/C expansion valve.

7. Install the nut (3) that secures the refrigerant line tapping block to the A/C expansion valve. Tighten the nut to 23 Nm (17 ft. lbs.).

8. On models equipped with the rear heating-A/C system, connect the underbody refrigerant line to the A/C suction line.

9. Install the right front wheelhouse splash shield.

10. Lower the vehicle.





11. Remove the tape or plugs from the opened suction line fitting and the compressor port.

12. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it and a new gasket onto the suction 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.

13. Install the A/C suction line (2) onto the A/C compressor (4).

14. Install the nut (1) that secures the A/C suction line to the A/C compressor. Tighten the nut to 23 Nm (17 ft. lbs.).

15. Reconnect the negative battery cable.

16. Evacuate the refrigerant system.

17. Adjust the refrigerant oil level.

18. Charge the refrigerant system.
