Ford FS-10 10-Cylinder

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 3-5 ounces, add amount drained plus one ounce of NEW refrigerant oil to replacement compressor. If amount drained is more than 5 ounces, add the same amount that was drained from old compressor. If amount drained is less than 3 ounces, add 3 ounces to compressor. See FORD FS-10 COMPONENT REFRIGERANT OIL CAPACITIES table. Add NEW 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.
