- If A/C flushing equipment is available, carry out the 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.
