Lincoln LS

Slowly discharge A/C system, using approved refrigerant recovery/recycling equipment. Remove A/C compressor. Drain as much compressor oil from suction and discharge ports as possible. Rotate compressor shaft 6-8 revolutions by hand, while pouring oil from ports. Collect oil in a clean container and measure amount drained. DO NOT reuse old refrigerant oil.
If amount drained is 3.0-5.0 ounces, add amount drained plus one ounce of refrigerant oil to replacement compressor. If amount drained is more than 5.0 ounces, add the same amount that was drained from old compressor. If amount drained is less than 3.0 ounces, add 3.0 ounces to compressor. See FORD SC90V COMPRESSOR COMPONENT REFRIGERANT OIL CAPACITIES table. Add refrigerant oil to replacement compressor through suction port.
Use new "O" rings on refrigerant lines. Install A/C compressor. Evacuate and charge system. Perform leak test. Ensure A/C system is operating properly.
