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.

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.

NOTE: The A/C suction line connects between the A/C evaporator and the A/C compressor. On models equipped with the rear heating-A/C system, the A/C suction line also includes an extension tube that connects the suction line to the underbody lines.





1. Install the A/C suction line (3) to the A/C compressor and the front A/C expansion valve.

2. Remove the tape or plugs from the refrigerant line coupler (6) and the underbody suction line.

3. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it onto the refrigerant line coupler. 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.

4. Connect the underbody suction line to the suction line extension tube (5).

5. Install the secondary retaining clip (2) onto the refrigerant line coupler.

6. Reconnect the negative battery cable.

7. Evacuate the refrigerant system.

8. Adjust the refrigerant oil level.

9. Charge the refrigerant system.
