The first step is to check that the refrigerant oil is in the right amount to avoid damage to the compressor. Whenever replacing several components, make sure to use the chart for the right amount of oil. Always put in new O-ring seals and gaskets on refrigerant lines when they are opened, so there are no leaks. The A/C suction line is serviced in two halves and its rear half is part of the same assembly as the rear A/C liquid line. For the front section, place the engine's A/C suction line into the suction line fitting, remove any rubber stoppers or tape, put a dual plane seal onto the line and lubricate the seal with clean oil. Fasten the front part to the rear with a nut that you tighten to 22 Nm. Take away the tape or obstructions from both fittings and around the A/C compressor, lubricate and mount a dual plane seal, then couple the suction line to the compressor and affix it with a nut turned to 23 Nm. Mount the air conditioner housing, put back the negative battery cable, release any refrigerant from the system, fill the right refrigerant oil and complete a charge. If you remove the rear section, place the A/C pressure transducer onto the A/C liquid line, set up the rear pieces of the suction and liquid lines, remove tape or plugs from the fittings, apply lubricant, insert new dual plane seals and join the lines to the
A/C Expansion Valve. Tighten the nut on the liquid and suction line tapping block to 23 Nm, use 11 Nm on the screw for the refrigerant line bracket and attach the wire harness to the A/C pressure transducer. Unplug the tape or plugs near the fittings between the front and rear on the liquid line, apply some lubricant to the seal, fit a new dual plane seal in place, connect the lines and tighten the nut to 22 Nm. Work through the same steps for the A/C suction line, then put on the air cleaner housing, attach the negative battery cable again, draw out any old refrigerant, set the oil to the desired level and charge the air-conditioning system.
