Compressor

Removal & Installation

CAUTION
If installing a new air conditioning compressor due to an internal failure of the old unit, you must flush the air conditioning system prior to installing a new air conditioning compressor.

CAUTION
Only refrigerant compressor oil (mineral oil) (F73Z-19577-AA/Motorcraft YN-9-A) should be used to lubricate R-134a refrigerant system O-ring seals and it should not be added to the R-134a refrigerant system as an A/C compressor lubricant. Only PAG refrigerant compressor oil (F7AZ-19589-DA/Motorcraft YN-12-C) or an equivalent meeting the manufacturer’s specification should be used as an A/C compressor lubricant.

NOTE: The compressor contains refrigerant oil. Do not allow the oil to drain out of the compressor. Any oil that drains out of the compressor must be replaced.

NOTE: Make sure to use O-rings specifically designed for R-134a systems.

To Remove:

1. Recover the refrigerant from the A/C system then remove the drive belt from the A/C compressor pulley.
2. Disconnect the electrical connector from the A/C compressor.
3. Disconnect the compressor manifold and tube assembly from the A/C compressor.
4. Remove the bolts and the A/C compressor.
5. Throw away the O-ring seals.

To Install:

1. Install the A/C compressor.
   • Torque to 18 ft-lb (25 Nm).
2. Use new O-rings and connect the compressor manifold and tube assembly.
   • Torque to 15 ft-lb (20 Nm).
3. Connect the A/C compressor electrical connector.
4. Install the drive belt.
5. Recharge the air conditioning system with the proper type and amount of refrigerant.
6. Check the operation of the air conditioning system.
