COMPRESSOR INSTALLATION

PROCEDURE


  1. INSPECT COMPRESSOR OIL


    1. A01V25A

      When replacing the compressor with motor assembly with a new one, gradually discharge the refrigerant 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: 115 to 130 cc (3.9 to 4.4 fl. oz.)) - (Remaining oil amount in the removed compressor with motor assembly) = (Oil amount to be removed from the new compressor)

      Note


      • When checking the compressor oil level, observe the precautions on the cooler removal/installation.

      • 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-OIL11 or equivalent compressor oil. If any compressor oil other than ND-OIL11 is used, compressor with motor assembly insulation performance may decrease, resulting in a leak of electric power.

  2. INSTALL COMPRESSOR WITH MOTOR ASSEMBLY


    1. Temporary install the compressor with motor assembly with the 2 stud bolts.

    2. A01UXVPE02

      Using "TORX" socket wrench (E8), install the stud bolts, in the order shown in the illustration.

      Torque:
      15 N*m  { 153 kgf*cm, 11 ft.*lbf }
    3. A01UYM1E01

      Tighten the bolt and 2 nuts in the order shown in the illustration.

      Torque:
      25 N*m  { 250 kgf*cm, 18 ft.*lbf }
    4. A01V1LXE01
      Text in Illustration
      *1 Green-colored Lock

      Connect the connector B.

    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.

      CAUTION:

      Make sure to wear insulating gloves.

      Note

      Make sure that the connector is connected securely.

  3. CONNECT SUCTION HOSE SUB-ASSEMBLY


    1. Remove the vinyl tape from the hose.

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

      Compressor oil
      ND-OIL11 or equivalent

    3. Install the O-ring onto the suction hose sub-assembly.

    4. Install the suction hose sub-assembly to the compressor with motor assembly with the bolt.

      Torque:
      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }

  4. CONNECT NO. 1 COOLER REFRIGERANT DISCHARGE HOSE


    1. Remove the vinyl tape from the hose.

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

      Compressor oil
      ND-OIL11 or equivalent

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

    4. Install the No. 1 cooler refrigerant discharge hose to the compressor with motor assembly with the bolt.

      Torque:
      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }
