REFRIGERANT LINE REMOVAL


  1. RECOVER REFRIGERANT FROM AIR CONDITIONING SYSTEM


    1. Turn the A/C switch on.

    2. Operate the air conditioning with a set temperature of 25°C (77°F) and the blower at low for 10 minutes to circulate the refrigerant. This causes most of the compressor oil from the various components of the air conditioning system to collect in the air conditioning compressor.

    3. Turn the ignition switch off.

    4. Recover the refrigerant from the air conditioning system using a refrigerant recovery unit.

  2. REMOVE PIPING CLAMP (for 1AZ-FE)

      *1 Suction pipe Sub-assembly
      *2 No. 1 Cooler Refrigerant Suction Hose
      *3 Piping Clamp
      *a Press In

      While pressing the end of the No. 1 cooler refrigerant suction hose to the end of the suction pipe sub-assembly, use pliers to squeeze together both sides of the piping clamp until it breaks apart.

      Note

      Make sure that fragments of the piping clamp do not enter the piping.

    2. Separate the No. 1 cooler refrigerant suction hose.

      Note

      Clean off any dirt or water near the ends of the No. 1 cooler refrigerant suction hose and suction pipe sub-assembly.

    3. Remove the 2 O-rings from the No. 1 cooler refrigerant suction hose.

      Note

      Wrap the open ends of the separated suction pipe sub-assembly and No. 1 cooler refrigerant suction hose with vinyl tape to prevent dirt or water from entering.
