2. Disconnect and isolate the negative battery cable.

A/C Expansion Valve:

3. Remove the nut that secures the A/C suction and liquid lines to the stud on the A/C expansion valve.
4. Disconnect the A/C suction and liquid lines from the A/C expansion valve and remove and discard the O-ring seals.
5. Disengage the routing clip retainer from the rear section of the A/C liquid line.

Receiver - Drier:

6. Remove the bolt that secures the rear section of the liquid line to the top of the receiver/drier.
7. Disconnect the rear section of the liquid line from the receiver/drier.
8. Remove the seal from the liquid line fitting outlet port and discard.
9. Install plugs in, or tape over the opened liquid and suction line fittings, both receiver/drier ports and both expansion valve ports.
10. Remove the rear section of the liquid line from the engine compartment.

INSTALLATION

NOTE: The A/C liquid line is serviced in two sections. The front section connects between the A/C condenser and the receiver/drier and includes the high side service port and the A/C pressure transducer on the fitting for the receiver/drier. The rear section connects between the receiver/drier and the A/C expansion valve.

1. Position the rear section of the A/C liquid line into the engine compartment.
2. Remove the tape or plugs from the liquid and suction line fittings, the receiver/drier outlet port and both expansion valve ports.
3. Lubricate new rubber O-ring seals with clean refrigerant oil and install them onto the suction and liquid line fittings for the expansion valve.
4. Connect the liquid line and suction line fittings to the A/C expansion valve.
5. Install the nut that secures the suction line and liquid line fittings to the stud on the A/C expansion valve. Tighten the nut to 10 N.m (89 in. lbs.).
6. Lubricate new rubber O-ring seal with clean refrigerant oil and install it on the liquid line fitting.
7. Connect the liquid line fitting to the receiver/ drier outlet port.
