1. If removed, install the A/C pressure transducer (8) onto the A/C liquid line (1).
2. Position the A/C liquid line into the engine compartment.
3. Remove the tape or plugs from the opened liquid line fittings and the condenser and evaporator ports.
4. Lubricate new O-ring seals with clean refrigerant oil and install them onto the liquid line spring-lock coupler fitting. Use only the specified O-ring
seals 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.
5. Connect the A/C liquid line to the evaporator inlet tube (3) See: Coupler HVAC/Service and Repair/Installation.
6. Install the secondary retaining clip (4) onto the spring-lock coupler that secures the A/C liquid line to the evaporator inlet tube.
7. Engage the A/C liquid line into the body retaining clips (5).
8. Lubricate a new O-ring seal with clean refrigerant oil and install it and a new gasket onto the liquid line fitting. Use only the specified O-ring seal
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.
9. Connect the A/C liquid line to the condenser outlet port (7).
10. Install the nut (6) that secures the A/C liquid line to the condenser outlet port. Tighten the nut to 23 Nm (17 ft. lbs.).

INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Service and Repair/Refrigerant Oil
Level. 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 systemSee: Service and Repair/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.
