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 suction hose sub-assembly.


  1. RECOVER REFRIGERANT FROM AIR CONDITIONING SYSTEM


    1. Turn the power switch on (READY).

    2. Turn the A/C switch on.

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

      Item Condition
      Engine Speed Idling
      Operating Time 3 minutes or more
      A/C Switch Status ON
      Blower Switch Status HI
      Set Temperature MAX COOL

      This cause 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.

    4. Turn the power switch off.

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

      Tech Tips

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