How to remove and replace the orifice tube in an air conditioning system on Ford Mustang?

A spring lock coupling tool is necessary to remove the orifice tube. The orifice tube changes the high-pressure liquid refrigerant into a low-pressure liquid. First, have the air conditioning system discharged by a dealer service department or by an automotive air conditioning shop. Then, remove the line clip and disconnect the condenser to evaporator line with a spring lock tool. Next, remove the orifice tube from the line with a pair of needle-nose pliers. If it's really stuck or breaks off, special extractor tools are available at most auto parts stores. The orifice tube is equipped with a tapered mesh screen that must be clean and free of damage. Installation is the reverse of removal. Be sure to remove and discard the old O-rings and replace them with new ones. Finally, take the vehicle back to the shop that discharged it. Have the system evacuated, recharged, and leak tested.
