REFRIGERANT LINE REMOVAL


  1. RECOVER REFRIGERANT FROM REFRIGERATION SYSTEM


    1. Start the engine.

    2. Operate the cooler compressor under the conditions shown below:

      Item Condition Indicator
      Operating Time 3 minutes or more -
      Temperature setting Max cool -
      Blower speed High A01G9SU
      Engine Idling -
      A/C switch On A01G57E

      This causes most of the compressor oil from the various components of the A/C system to collect in the A/C compressor.

      Tech Tips

      It is not necessary to operate the cooler compressor if the A/C does not operate because of compressor lock, etc.

    3. Stop the engine.

    4. Recover the refrigerant from the A/C system using a refrigerant recovery unit.

      Tech Tips

      Use the refrigerant recovery unit in accordance with the manufacturer's instruction manual.

  2. REMOVE PIPING CLAMP


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

      Note


      • If any foreign matter is adhered to the connecting part, brush it off or use compressed air to remove it.

      • 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 moisture or foreign matter 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 the entry of moisture and foreign matter.
