Ford Focus Service Manual: Air Conditioning (A_C) Compressor

Removal and Installation

NOTICE: If installing a new Air Conditioning (A/C) compressor due to an internal failure of the old unit, the following procedures must be carried out to remove contamination from the A/C system. Failure to remove contamination from the A/C system, if present, will result in poor A/C system performance and/or damage to the new A/C compressor and other components.

• If A/C flushing equipment is available, carry out the A/C system flushing procedure prior to installing a new A/C compressor. For additional information, refer to Section  412-00.
• If A/C flushing equipment is not available, carry out the refrigerant system filtering procedure following A/C compressor installation. For additional information, refer to Section  412-00.
• Install a new Thermostatic Expansion Valve (TXV) , as directed by the A/C flushing or filtering procedure.
• Install a new receiver/drier as directed by the A/C flushing or filtering procedure.

NOTE:

Installation of a new receiver/drier is not required when repairing the A/C system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier. Damage to the receiver/drier includes leaks in the receiver/drier, physical damage to the receiver/drier shell or desiccant, or moisture contamination. Moisture contamination results only from a complete loss of refrigerant, and equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If even a slight amount of positive refrigerant pressure is present, and physical evidence of contamination from an A/C compressor failure is not present in the system before repairs are carried out, a new receiver/drier should not be installed.

All vehicles

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section  100-02.

1. Recover the refrigerant. For additional information, refer to Section  412-00.

1. NOTE:

   The A/C compressor discharge line is held in place by a bracket attached to the lower rear A/C compressor stud-bolt. The A/C compressor discharge fitting cannot be easily disconnected until later in this procedure when the bracket is detached.

   Remove the A/C compressor suction and discharge fitting nuts and disconnect the suction fitting.

   • Discard the O-ring seal and gasket seal.
   • To install, tighten to 15 Nm (133 lb-in).

Vehicles with manual transmission

1. Remove the engine cooling fan assembly. For additional information, refer to Section  303-03.

Vehicles with automatic transmission

1. Remove the lower radiator air deflector. For additional information, refer to Section  501-02.

All vehicles

1. Remove the 2 drive belt shield bolts and remove the shield.

1. Release the tensioner and remove the drive belt from the A/C compressor pulley.

1. Remove the power steering line bracket nut at the transmission.
   • To install, tighten to 9 Nm (80 lb-in).

1. Remove the compressor-to-condenser discharge line bracket nut from the lower rear A/C compressor stud-bolt and detach the discharge line and power steering line brackets.
   • To install, tighten to 9 Nm (80 lb-in).

1. Disconnect the A/C compressor discharge fitting.
   • Discard the O-ring seal and gasket seal.

1. Disconnect the clutch field coil electrical connector.

1. Remove the 2 A/C compressor bolts and the A/C compressor stud-bolt.
   • To install, tighten to 25 Nm (18 lb-ft).

1. Remove the A/C compressor.

1. To install, reverse the removal procedure.
   • Install new gasket seals and O-ring seals.
   • Lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to Section  412-00.

1. Evacuate, leak test and charge the refrigerant system. For additional information, refer to Section  412-00.
