INSTALLATION 

LHD MODELS 

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C 

refrigerant system. See 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.

1. Remove the tape or plugs from the opened refrigerant line fittings and the condenser and expansion valve 

ports.  

2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them onto the refrigerant 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. Connect the A/C liquid line (1) to the condenser tube (2) and install the secondary retaining clip. See 

INSTALLATION. 

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. See 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.
