A/C Compressor and Clutch Assembly

2005 Ford Taurus SEL, 4D SedanSECTION A/C Compressor and Clutch Assembly
WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Internal A/C compressor components are not serviced separately. The variable scroll compressor is serviced only as an assembly. The A/C clutch, A/C clutch pulley and the A/C clutch field coil are serviceable.

The variable scroll A/C compressor has the following characteristics:

  • A variable capacity function controlled by a suction pressure sensing device.
  • A fixed and orbiting scroll to provide refrigerant compression.
  • A non-serviceable shaft seal.
  • The A/C compressor uses PAG Refrigerant Compressor Oil YN-12-D WSH-M1C231-B. This oil contains special additives necessary for the A/C compressor.

The A/C compressor contains a thermal cutout switch which senses the compressor housing temperature. The switch will disengage the A/C compressor clutch if the housing temperature exceeds 120°C (247°F).

The magnetic A/C clutch has the following characteristics:

  • It drives the compressor shaft.
  • When battery positive voltage (B+) is applied to the A/C clutch field coil, the clutch disc and hub assembly is drawn toward the A/C clutch pulley.
  • The magnetic force locks the clutch disc 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 disc and hub assembly move the clutch disc away from the A/C clutch pulley.
