COMPRESSOR INSTALLATION


  1. ADJUST COMPRESSOR OIL LEVEL


    1. A01EKA2

      When replacing the cooler compressor assembly with a new one, gradually discharge the inert gas (helium) from the service valve, and drain the following amount of oil from the vents indicated by the arrows in the illustration before installation.

      Tech Tips

      The drain bolt and washer can be reused.

      Standard
      (Oil capacity inside the new compressor assembly with pulley: 130 + 15 cc (4.4 + 0.51 fl.oz.) ) - (Remaining oil amount in the removed compressor assembly with pulley) = (Oil amount to be removed from the new compressor when replacing)

      Note


      • If a new compressor is installed without removing some oil remaining in the pipes of the vehicle, the oil amount will be excessive. This prevents heat exchange in the refrigerant cycle and causes refrigeration system failure.

      • If the volume of oil remaining in the removed compressor is too small, check for oil leaks.

      • Be sure to use ND-OIL 8 or equivalent for compressor oil.

  6. INSTALL V-RIBBED BELT


    1. A01EJPME03
      Text in Illustration
      *1 Generator
      *2 Tensioner
      *3 Crankshaft
      *4 Water Pump
      *5 Cooler Compressor

      Set the V-ribbed belt onto each part as shown in the illustration except the water pump pulley.

    2. Loosen the V-ribbed belt by turning the belt tensioner clockwise.

    3. Set the V-ribbed belt onto the water pump pulley.

      Note

      Make sure that the belt is attached to each pulley. In particular, make sure that the belt is securely fitted into the grooves of the crankshaft pulley.

  7. INSTALL FRONT FENDER APRON SEAL RH


    1. A01EITO

  10. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.

  11. CHARGE WITH REFRIGERANT


    1. Perform vacuum purging using a vacuum pump.

    2. Charge with refrigerant HFC-134a (R134a).

      Standard
      450 to 550 g (15.9 to 19.4 oz.)
      SST
      09985-20010   ( 09985-02010, 09985-02050, 09985-02060, 09985-02070, 09985-02080, 09985-02090, 09985-02110, 09985-02130, 09985-02140, 09985-02150 )

      Note

      Do not turn the A/C switch on before charging with refrigerant. Doing so will cause the compressor to work without refrigerant, resulting in overheating of the compressor.

      Tech Tips

      Ensure that sufficient refrigerant is available to recharge the system when using a refrigerant recovery unit. Refrigerant recovery units are not always able to recover 100% of the refrigerant from an A/C system.

  12. WARM UP ENGINE


    1. Keep the A/C switch on for at least 2 minutes to warm up the compressor.

      Note

      Be sure to warm up the compressor when turning the A/C switch on after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.

  13. INSPECT FOR REFRIGERANT LEAK


    1. After recharging with refrigerant, inspect for refrigerant leaks using a halogen leak detector.

    2. Carry out the test under the following conditions:


      • Turn the ignition switch off.

      • Secure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as evaporated gasoline and exhaust gas).

      • Repeat the test 2 or 3 times.

      • Make sure that there is some refrigerant remaining in the refrigeration system.

        When the compressor is off: approx. 392 to 588 kPa (4.0 to 6.0 kgf/cm2, 57 to 85 psi)

      *1 Halogen Leak Detector

      Using a halogen leak detector, inspect for refrigerant leaks from the refrigerant lines.

    4. A01EJA9E08

      *1 Halogen Leak Detector
      *2 Drain Hose

      Bring the halogen leak detector close to the drain hose with the detector's power off, and then turn the detector on.

      Tech Tips


      • After the blower motor has stopped, let the cooling unit stand for more than 15 minutes.

      • Bring the halogen leak detector sensor under the drain hose.

      • When bringing the halogen leak detector close to the drain hose, make sure that the halogen leak detector does not react to volatile gases. If it is not possible to avoid interference from volatile gases, the vehicle should be lifted up to allow testing.

    5. If a refrigerant leak is not detected from the drain hose, remove the blower motor control from the cooling unit. Insert the halogen leak detector sensor into the unit and perform the test.

    6. Disconnect the pressure switch connector and leave it for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.

  14. INSTALL NO. 1 ENGINE UNDER COVER
