    INSPECT COMPRESSOR OIL


    1. A01MRPG

      When replacing the compressor with motor assembly with a new one, gradually discharge the inert gas from the service valve, and drain the following amount of oil from the new compressor with motor assembly before installation.

      Standard
      (Oil capacity inside the new compressor with motor assembly: 120 to 135 cc (4.1 to 4.5 fl. oz.)) - (Remaining oil amount in the removed compressor with motor assembly) = (Oil amount to be removed from the new compressor)
      Note:

      • If a new compressor with motor assembly is 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 ineffective cooling.

      • If the amount of oil remaining in the old compressor with motor assembly is too small, check the air conditioning system for oil leaks.

      • Be sure to use ND-OIL 11 or equivalent compressor oil. If any compressor oil other than ND-OIL 11 is used, compressor with motor assembly insulation performance may decrease, resulting in a leakage of electric power.

    INSTALL COMPRESSOR WITH MOTOR ASSEMBLY


    1. Using an E8 "TORX" socket wrench, install the stud bolt.

      10 N*m 102 kgf*cm 7 ft.*lbf
      Tip:

      Tighten the stud bolt.

    2. A01MRWLC03
      B003XUN Bolt
      B003YHT Nut

      Install the compressor with motor assembly with the 2 bolts and nut.

      24.5 N*m 250 kgf*cm 18 ft.*lbf
      Tip:

      Tighten the 2 bolts and nut in the order shown in the illustration.

    3. Connect the No. 1 inverter cooling pipe assembly with the 2 bolts.

      22 N*m 224 kgf*cm 16 ft.*lbf
    4. A01MTWLC02
      *a Connector A
      *b Connector B
      *c Green-colored Lock

      Connect the connector B.

    5. Connect the connector A and slide the green-colored lock as shown in the illustration to lock it securely.

      CAUTION:

      Make sure to wear insulating gloves.

      Note:

      Make sure that the connector is connected securely.

    CONNECT NO. 1 COOLER REFRIGERANT DISCHARGE HOSE


    1. Remove the vinyl tape from the No. 1 cooler refrigerant discharge hose.

    2. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor with motor assembly.

      Compressor Oil
      ND-OIL 11 or equivalent

    3. Install the O-ring to the No. 1 cooler refrigerant discharge hose.

      Note:

      • Keep the O-ring and O-ring fitting surface free of 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 No. 1 cooler refrigerant discharge hose to the compressor with motor assembly with the bolt.

    CONNECT SUCTION HOSE


    1. Remove the vinyl tape from the suction hose.

    2. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor with motor assembly.

      Compressor Oil
      ND-OIL 11 or equivalent

    3. Install the O-ring to the suction hose.

      Note:

      • Keep the O-ring and O-ring fitting surface free of 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 suction hose to the compressor with motor assembly with the bolt.
