A/C Compressor And Clutch Assembly

WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Internal A/C compressor components are not repaired separately. The Visteon FS-10 A/C compressor is repaired only as an assembly. The A/C clutch disc and hub assembly, A/C clutch pulley, A/C clutch field coil and the compressor shaft seal are repairable.

NOTE: Installation of a new suction accumulator/drier is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator/drier.

The Visteon FS-10 A/C compressor (19703) 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 changes 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 a dark color while maintaining a normal oil viscosity. This is normal for this A/C compressor because carbon from the piston rings will discolor the oil.
