How to remove and install the orifice tube in an air conditioning system?

Have the air conditioning system discharged by a dealer service department or an automotive air conditioning shop before proceeding. Disconnect the fitting in the refrigerant line from the condenser to the evaporator. Use an open-end wrench on the stationary fitting and a flare nut wrench to avoid rounding off the tube nut. Remove the orifice tube from the line with a pair of needle-nose pliers. If it's stuck or breaks off, special extractor tools are available at most auto parts stores. Installation is the reverse of removal. Be sure to remove and discard the old O-rings. Take the vehicle back to the shop that discharged it. Have the system evacuated, recharged and leak tested.
