CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Service and
Repair/Procedures/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/Procedures/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.
1. Remove the tape or plugs from the opened discharge line fittings and compressor and condenser ports.
2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the discharge line fittings. Use only the
specified O-rings 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.
3. For clearance, position the A/C condenser (3) toward the left side of the vehicle.
4. Connect the A/C discharge line (5) to the A/C condenser and install the retaining nut (4) hand tight.
5. Reposition the A/C condenser and install the bolt (2) that secures the condenser to the right side of the radiator (1). Tighten the bolt to 5 Nm (44
in. lbs.).
6. Tighten the nut that secures the A/C discharge line to the A/C condenser to 22.5 Nm (200 in. lbs.).
7. Install the grille See: Body and Frame/Grille/Service and Repair/Grille - Installation.
8. Connect the A/C discharge line (3) to the A/C compressor (4).
