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 liquid line is serviced in two sections. The front section connects between the A/C condenser and the receiver/drier. The rear section
connects between the receiver/drier and the A/C expansion valve. On models equipped with the rear heating-A/C system, the rear section of the A/C
liquid line also includes an extension tube that connects the liquid line to the underbody lines.
FRONT SECTION
1. Position the front section of the A/C liquid line (2) into the engine compartment.
2. Remove the tape or plugs from the liquid line fitting and the condenser port.
3. Lubricate a new rubber 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 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 A/C liquid line to the A/C condenser (3).
