COOLER EXPANSION VALVE REMOVAL

Note

When removing the cooler expansion valve by itself, be sure to install a new cooler expansion valve and new bolt for the suction pipe sub-assembly.


  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.
