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, see 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.
NOTE: The A/C liquid line is serviced in two sections.
FRONT SECTION
1. Position the front section of the A/C liquid line (1) into the engine compartment.
2. Remove the tape or plugs from the opened ends of the A/C liquid lines and the condenser port.
3. Lubricate new O-ring seals with clean refrigerant oil and install them onto the front 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.
4. Connect the front section of the A/C liquid line to the rear section of the liquid line (3)Refrigerant Line Coupler - Installation.
5. Install the secondary retaining clip (2) onto the spring-lock coupler that secures the front section of the A/C liquid line onto the rear section of the liquid line.
6. Engage the A/C liquid line (1) into the three body retaining clips (2 and 3) located at the right front corner of the engine compartment.
7. Lubricate a new O-ring with clean refrigerant oil and install it and a new gasket onto the front 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.
8. Connect the front section of the A/C liquid line (2) to the condenser port.
9. Install the nut (1) that secures the A/C liquid line to the A/C condenser (3). Tighten the nut to 23 Nm (17 ft. lbs.).
10. Position the air seal over the right end of the A/C condenser and install the air seal retainers.
11. Install the passenger side battery tray Battery Tray - Installation.
12. Reconnect the negative battery cable(s).
13. Evacuate the refrigerant system Refrigerant System Evacuate.
14. Adjust the refrigerant oil level Refrigerant Oil Level.
15. Charge the refrigerant system Refrigerant System Charge.
REAR SECTION
1. Position the rear section of the A/C liquid line (2) into the engine compartment.
2. Remove the tape or plugs from the opened ends of the A/C liquid lines and the evaporator tube (4).
3. Lubricate new O-ring seals with clean refrigerant oil and install them onto the rear 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.
4. Connect the rear section of the A/C liquid line to the evaporator tube Refrigerant Line Coupler - Installation.
5. Install the secondary retaining clip (3) onto the spring-lock coupler that secures the rear section of the A/C liquid line onto the evaporator tube.
6. Engage the A/C liquid line into the body retaining clip (5).
7. Lubricate new O-ring seals with clean refrigerant oil and install them onto the front liquid line spring-lock coupler fitting. Use only the specified 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.
8. Connect the rear section of the A/C liquid line (6) to the front section of the liquid line Refrigerant Line Coupler - Installation.
9. Install the secondary retaining clip (1) onto the spring-lock coupler that secures the front section of the A/C liquid line to the rear section of the liquid line.
10. Install the passenger side battery tray Battery Tray - Installation.
11. Reconnect the negative battery cables.
12. Evacuate the refrigerant system Refrigerant System Evacuate.
13. Adjust the refrigerant oil level Refrigerant Oil Level.
14. Charge the refrigerant system Refrigerant System Charge.
