Ford Mustang (1999-2004) Service Manual: A/C Compressor and Clutch Assembly
NOTE: Internal A/C compressor components are not serviced separately. The FS-10 A/C compressor is serviced only as an assembly. The A/C clutch pulley, A/C clutch field coil (19D798) and the shaft seal are serviceable.
The FS-10 A/C compressor has the following characteristics:
- A ten-cylinder swashplate design utilizing the tangential design mount.
- A one-piece lip-type seal (installed from the front of the A/C compressor) is used to seal it at the shaft opening in the assembly.
- Five double-acting pistons operate within the cylinder assembly. The pistons are actuated by a swashplate that converts the rotating action of the shaft to a reciprocating force.
- Reed-type discharge valves are located between the cylinder assembly and the head at each end of the A/C compressor.
- The A/C compressor uses PAG oil, or equivalent. This oil contains special additives required for the A/C compressor.
- The A/C compressor oil from vehicles equipped with an FS-10 A/C compressor may have some dark colored streaking while maintaining a normal oil viscosity. This is normal for the A/C compressor and is caused by break-in wear of the piston rings.
The magnetic A/C clutch has the following characteristics:
- It drives the compressor shaft.
- When the battery positive voltage (B+) is applied to the A/C clutch field coil, the clutch plate and hub assembly is drawn toward the A/C clutch pulley.
- The magnetic force locks the clutch plate and hub assembly and the A/C clutch pulley together as one unit, causing the compressor shaft to rotate.
- When (B+) is removed from the A/C clutch field coil, springs in the clutch plate and hub assembly move the clutch plate away from the A/C clutch pulley.
Air Conditioning (Description and Operation)
The A/C refrigerant system is a clutch cycling orifice tube type. The system
components are:
