Section 41 (Air Conditioning System (Service Information)): Compressor: Installation: Installation

WARNING: This page is about a different car, the 2012 Lexus CT 200h. However, it is still accessible from the selected car via links, so may be relevant.
  1. ADJUST COMPRESSOR OIL 
    1. When replacing the electric inverter compressor with a new one, gradually discharge the gas from the service valve of the new compressor, and drain the following amount of oil from the new electric inverter compressor before installation.

      Standard

      (Oil capacity inside the new electric inverter compressor: 130 to 145 cc (4.4 to 4.9 fl. oz.)) - (Remaining oil amount in the removed electric inverter compressor) = (Oil amount to be removed from the new compressor when replacing)

      NOTE:
      • When checking the compressor oil level, observe the precautions on the air conditioning Refrigerant-Replacement.
      • If a new compressor and magnetic clutch are installed without removing some oil, there will be too much oil in the system due to the oil remaining in the pipes of the vehicle. Excessive oil in the system prevents heat exchange in the refrigeration cycle and causes refrigeration failure.
      • If the amount of oil remaining in the old compressor is too small, check the A/C system for oil leaks.
      • Be sure to use ND-OIL 11 or equivalent for compressor oil. If any compressor oil other than ND-OIL 11 is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.
  2. INSTALL ELECTRIC INVERTER COMPRESSOR 
    1. Using an E8 "TORX" socket wrench, temporarily install the electric inverter compressor with the 2 stud bolts.

      Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf) 

    2. Temporarily install the bolt and 2 nuts.
    3. Install the electric inverter compressor with the bolt and 2 nuts.

      Torque: 25 N*m (250 kgf*cm, 18 ft.*lbf) 

      NOTE:

      Tighten the bolts in the order shown in the illustration to install the electric inverter compressor.

    4. Connect the connector <B>.

      *1 Green-colored Lock
    5. Connect the connector <A> and slide the green-colored lock in the direction indicated by the arrow in the illustration to lock it securely.
      WARNING:

      Make sure to wear insulating gloves.

      NOTE:

      Make sure that the connector is connected securely.

  3. CONNECT COOLER REFRIGERANT SUCTION HOSE 
    1. Remove the vinyl tape from the hose.
    2. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the electric inverter compressor.

      Compressor oil

      ND-OIL 11 or equivalent

    3. Install the O-ring onto the cooler refrigerant suction hose.
      NOTE:
      • Keep the O-ring and O-ring fitting surfaces free from dirt or foreign matter.
      • 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.
    4. Install the cooler refrigerant suction hose onto the electric inverter compressor with the bolt.

      Torque: 9.8 N*m (100 kgf*cm, 87 in.*lbf) 

  4. CONNECT COOLER REFRIGERANT DISCHARGE HOSE 
    1. Remove the attached vinyl tape from the hose.
    2. Apply a sufficiently amount of compressor oil to a new O-ring and the fitting surface of the electric inverter compressor.

      Compressor oil

      ND-OIL 11 or equivalent

    3. Install the O-ring onto the cooler refrigerant discharge hose.
      NOTE:
      • Keep the O-ring and O-ring fitting surfaces free from dirt or foreign matter.
      • 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.
    4. Install the cooler refrigerant discharge hose onto the electric inverter compressor with the bolt.

      Torque: 9.8 N*m (100 kgf*cm, 87 in.*lbf)
