Refrigerant Filter: Service and Repair
A/C REFRIGERANT SYSTEM FILTERING
NOTE: Two A/C service kits have been released to provide the necessary equipment and information to perform the new, mandatory A/C system
filtering procedure. Filter kits with the service part number suffix "A" are to be used on vehicles that have a nylon lined suction hose between the suction
accumulator/drier and the compressor. Filter kits with the service part number suffix "B" are for vehicles with a rubber lined suction hose.
CAUTION: Follow all the refrigerant system safety and service precautions.
INSTALLATION
1. To Determine that the compressor has failed and the system must be filtered, recover the refrigerant from the A/C system and remove the orifice
tube and liquid line, if necessary. Look for a dirty orifice tube and/or a liquid line containing black refrigerant oil and particles.
2. Remove the damaged compressor and drain the oil into a calibrated container.
NOTE: The proper amount of refrigerant oil must be added to the new compressor before it can be installed.
3. Install the new compressor. Be sure the compressor mounting bolts are tightened to the proper specification. Check the tension of the compressor
drive belt. Adjust, if necessary.
4. Remove the suction accumulator/drier assembly and drain the oil into a calibrated container.
5. Add clean refrigerant oil to the new accumulator/drier in the same amount that was removed from the old unit, plus an additional 60 ml (2 oz) of
new refrigerant oil.
6. Install the suction accumulator/drier in the vehicle.
7. Determine the type of suction hose with which you are working. To do this, cut the suction hose into two pieces (make the cut closer to the
compressor than the accumulator) and measure the hose wall thickness. Rubber lined hose has a wall thickness of 1/4 inch and nylon lined hose
has a wall thickness of 1/8 inch.
8. Get the proper service kit for the vehicle. Filter kits with the service part number suffix "A" are to be used on vehicles with a nylon lined suction
hose. Filter kits with the service part number suffix "B" are for vehicles with rubber lined suction hose. The label on the filter shows which hose it
is to be used with.
