BODY CODE DESIGNATIONS - LIGHT TRUCKS & VANS
REFRIGERANT OIL
Only new, pure, moisture-free refrigerant oil should be used in A/C systems. This oil is highly refined with a very low moisture content. Oil container must be tightly closed at all times when not in use, or moisture from the air will be absorbed into the refrigerant oil.
On systems with HFC-134a refrigerant, use Polyalkylene Glycol (PAG) wax-free refrigerant oil.
DISCHARGING SYSTEM
| CAUTION | When discharging air conditioning system, use only approved refrigerant recovery/recycling equipment. Make every attempt to avoid discharging refrigerant into the atmosphere. |
If compressor has stem-type service valves, it can be isolated and removed without discharging entire system. Otherwise, discharge system completely using approved refrigerant recovery/recycling equipment before loosening any fittings.
DISCONNECTING LINES & FITTINGS
After system is discharged, carefully clean area around all fittings to be opened. Always use 2 wrenches when tightening or loosening fittings. Some refrigerant lines are connected with a coupling. Special tools may be required to disconnect lines. Cap or plug all openings as soon as lines are removed. DO NOT remove caps until connections of lines and fittings are completed.
Note. All HFC-134a based systems use 1/2-16 ACME threaded fittings.
CONNECTING LINES & FITTINGS
Note. Different fittings and connections are used on systems using HFC-134a refrigerant. Ensure all replacement parts match the connections of the system being worked on.
Always use a new gasket or "O" ring when connecting lines or fittings. Coat "O" ring with refrigerant oil and ensure it is not twisted during installation. Always use 2 wrenches to prevent damage to lines and fittings.
FORD FS-6 6-CYLINDER & FX-15 10-CYLINDER
- Slowly discharge system using approved refrigerant recovery/recycling equipment. Remove A/C compressor. Drain compressor oil from suction, and discharge ports. Measure amount drained, and discard oil.
- If amount drained is 3-5 ounces, add drained amount of new refrigerant oil (use only Motorcraft Refrigeration Oil YN-9) into compressor through suction port.
- If amount drained is less than 3 ounces, add 3 ounces. If amount drained is more than 5 ounces, add 5 ounces. Use new "O" rings on refrigerant lines. Install A/C compressor. Evacuate and recharge system. Perform leak test.
Probe
On 3.0L models with 10P15 compressor, information is not available from manufacturer. On 2.2L models with 10P15A compressor, add specified amounts if components are changed. See 10P15 & 10P15A COMPONENT REFRIGERANT OIL CAPACITIES (PROBE) table. No other information is available from manufacturer.

Except Probe
- Start and operate engine at high idle with A/C on for 15 minutes. Stop engine. Slowly discharge system using approved refrigerant recovery/recycling equipment. Remove A/C compressor. Drain compressor oil. Measure amount drained, and discard oil.
- If amount drained is 3-5 ounces, add drained amount into compressor through suction port using new refrigerant oil. If amount drained is less than 3 ounces, add 3 ounces.
- If amount drained is more than 5 ounces, add 5 ounces. Use new "O" rings on refrigerant lines. Install A/C compressor. Evacuate and recharge system. Perform leak test.
