Acura 80220-ST7-A12 Expansion Valve Assembly (10N)

Have the air conditioning system discharged by a dealer service department or automotive air conditioning repair facility. Disconnect the cable from the negative terminal of the battery. Disable the airbag, if equipped. Caution: If the radio in your vehicle is equipped with an antitheft system, make sure you have the correct activation code before disconnecting the battery. Disconnect the two lines from the evaporator. Plug both lines to prevent the entry of contaminants and moisture into the air conditioning system. Remove the glovebox and the glovebox frame. Disconnect the electrical connector from the air conditioning thermostat and remove the wiring harness clips from the evaporator housing. Remove the evaporator unit retaining screws and nuts, pull the evaporator unit out far enough to disconnect the drain hose and remove the unit from the vehicle. Remove the screws and clips retaining the evaporator case halves together, remove the air conditioning thermostat and separate the housing. Remove the evaporator core from the housing and remove the expansion valve, if necessary. Installation is the reverse of removal. Have the system evacuated, charged and leak tested by a dealer service department or automotive air conditioning repair facility. If a new evaporator was installed, add 1-1/3 ounces of refrigerant oil.
