Good evening.

The compressor comes out the bottom and it is very tight.

Procedure below and pictures attached.

Removal

Caution:
- If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system.
- If A/C flushing equipment is available, carry out flushing of the air conditioning system prior to installing a new air conditioning compressor.
- If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed.
- Install a new thermostatic expansion valve, 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.
- Install a new auxiliary in-line filter in the auxiliary evaporator inlet line connection at the floorpan bracket.
- Refrigerant Compressor Oil (mineral oil) F73Z-19577-AA (Motorcraft YN-9-A) should be used to lubricate R-134a refrigerant system O-ring seals only and should not be added to the R-134a refrigerant system as an A/C compressor lubricant. PAG Refrigerant Compressor Oil F7AZ-19D589-DA (Motorcraft YN-12-C) or equivalent meeting Ford specification WSH-M1C231-B only should be used as an A/C compressor lubricant.

Note:
- Installation of a new receiver/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 receiver/drier.
- New o-ring seals, lubricated in clean mineral oil, must be installed before reconnecting any A/C fitting which has been disconnected.

1. Position the vehicle on a hoist with the gear selector in neutral.
2. If flushing of the air conditioning system has not been performed, recover the refrigerant.
3. Remove the drive belt from the A/C compressor pulley.

Installation:

1. To install, reverse the removal procedure.
2. If filtering of the air conditioning system is not to be performed, lubricate the refrigerant system with the correct amount of clean PAG oil.
3. If filtering of the air conditioning system is not to be performed, evacuate, leak test and charge the refrigerant system.
