A/C Liquid Line - Installation






INSTALLATION

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system 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 systemRefrigerant Oil Level .

NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. 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 (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) Refrigerant Line Coupler - 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.).
11. Install the air filter housing.
12. Connect the wire harness connector (2) to the A/C pressure transducer.
13. Reconnect the negative battery cable.
14. Evacuate the refrigerant system Refrigerant System Evacuate.
15. Adjust the refrigerant oil level Refrigerant Oil Level.
16. Charge the refrigerant systemRefrigerant System Charge.
