How to replace Compressor On Ford Mustang?

Compressor Removal & Installation details for 4.0L ENGINE
4.6L ENGINE Ford Mustang.


WARNING
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 evaporator core orifice as directed by the A/C flushing or filtering procedure.
Install a new suction accumulator as directed by the A/C flushing or filtering procedure.


NOTE
Installation of a new suction accumulator 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.
