1. INSTALL AIR CONDITIONING PRESSURE SENSOR

  1. Apply a sufficient amount of compressor oil to a new air conditioning pressure sensor.

    Compressor oil:
    ND-OIL 11 or equivalent

    NOTICE:
    1. Keep the O-ring and O-ring fitting surfaces free from dirt or foreign matter.
    2. Do not use any compressor oil other than ND-OIL 11 or equivalent. If any compressor oil other than ND-OIL 11 or equivalent is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.

  1. Install the new air conditioning pressure sensor.

    Torque:
    11 N*m{ 110 kgf*cm , 8 ft.*lbf }

    NOTICE:
    1. Do not deform the piping.
    2. Make sure to confirm that the piping does not disengage from the plastic clamp.

  1. Connect the connector.



2. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

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



3. INSTALL REAR FLOOR BOARD UPPER NO. 3 PLATE

  1. Engage the 4 claws and 2 guides to install the rear floor board upper No. 3 plate.



4. INSTALL DECK FLOOR BOX RH

  1. Engage the 6 guides.

  1. Install the deck floor box RH with the clip.



5. INSTALL REAR NO. 3 FLOOR BOARD

  1. Install the rear No. 3 floor board.



6. INSTALL REAR DECK FLOOR BOX

  1. Install the rear deck floor box.



7. INSTALL REAR NO. 2 FLOOR BOARD

  1. Install the rear No. 2 floor board.



8. CHARGE AIR CONDITIONING SYSTEM WITH REFRIGERANT

  1. Perform vacuum purging using a vacuum pump or appropriate equipment.



  1. Charge the air conditioning system with refrigerant.

    Refrigerant type:
    HFC-134a (R134a)



    E143108E09

    Standard charge amount:
    470 g (16.6 oz.)

    SST
    09985-20010   (09985-02010, 09985-02050, 09985-02060, 09985-02070, 09985-02080, 09985-02090, 09985-02110, 09985-02130, 09985-02140, 09985-02150)

    NOTICE:
    1. Do not turn the A/C switch on before charging the air conditioning system with refrigerant. Doing so may cause the compressor to work without refrigerant, resulting in overheating of the compressor.
    2. The refrigerant amount should be checked by quantity (weight).
    3. The graph above is shown for reference only. This vehicle is not equipped with a sight glass.
    4. If at all possible, avoid using a manifold gauge set or recovery and recycling unit that has been used for vehicles with conventional compressor oil (ND-OIL 8 or equivalent). If either of these is used, conventional compressor oil remaining in the equipment will enter the air conditioning system of the vehicle, resulting in electrical insulation performance deterioration. A manifold gauge set that has been used 3 times or less can be used if an appropriate one is not available.

    HINT:
    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 air conditioning system.



9. WARM UP COMPRESSOR

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

    NOTICE:
    To prevent damage to the compressor, be sure to warm up the compressor when turning the air conditioning on after removing and installing air conditioning system lines (including the compressor).



10. INSPECT FOR REFRIGERANT LEAK

  1. After recharging the air conditioning system with refrigerant, inspect for refrigerant leaks using a halogen leak detector.

  1. Carry out the test under the following conditions:

    1. Power switch off.
    2. Secure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as gasoline vapor and exhaust gas).
    3. Repeat the inspection 2 or 3 times.
    4. Measure the pressure to make sure that there is some refrigerant remaining in the air conditioning system.
      Pressure when the compressor is off: approx. 392 to 588 kPa (3.9 to 5.9 kgf/cm2, 57 to 85 psi)

  1. Using a halogen leak detector, inspect for refrigerant leaks from the air conditioning system.

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

    HINT:
    1. After the blower motor has stopped, leave the cooling unit for more than 15 minutes.
    2. Bring the halogen leak detector sensor under the drain hose.
    3. 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 checking for leaks.

  1. 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 check for a leak.

  1. Disconnect the pressure sensor connector and leave it for approximately 20 minutes. Bring the halogen leak detector close to the pressure sensor and check for a leak.

    HINT:
    When checking for leaks, the presence of oily dirt at a joint can indicate a leak.
