   *b

   Intake Port

   1. When replacing the compressor with motor assembly with a new one, drain the following amount of oil from the position shown by the arrow in the illustration before installing the new compressor with motor assembly.

      Standard

      (Oil capacity inside the new compressor with motor assembly: 220 to 235 cc (7.44 to 7.94 fl.oz)) - (Remaining oil amount in the removed compressor with motor assembly) - 65 cc (2.20 fl.oz) = (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 leakage of electric power.
      • Make sure to drain compressor oil from the intake port.
      • Make sure to add compressor oil from the intake port.
      • If the amount of oil from the removed compressor with motor assembly plus an additional 65 cc (2.20 fl.oz) is then greater than the amount of oil in a new compressor with motor assembly, do not drain the compressor oil from the new compressor with motor assembly.
      • When it is not possible to confirm the amount of oil in the system such as when compressor oil is spilt due to damage caused by a vehicle collision, etc., install a new compressor without draining any oil. If also replacing the cooler condenser assembly, do not add the supplied oil (40 cc (1.35 fl.oz)).

   1. Install the compressor with motor assembly using the following procedure.

      1. Using an E8 "TORX" socket wrench, temporarily install the compressor assembly with pulley with the 2 stud bolts.

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

      2. Install the compressor assembly with pulley with the bolt and 2 nuts in the order shown in the illustration.

      Torque: 24.5 N*m (250 kgf*cm, 18 ft.*lbf)

   *c	Green-colored Lock	-	-
   	Slide	-	-

   1. Connect the connector (B).
   2. Attach the clamp.
   3. Remove the insulating tape from the connector (A) and connect the connector (A) and slide the green-colored lock as shown in the illustration to securely lock it.
      WARNING:

      Make sure to wear insulated gloves.

      NOTE:

      Make sure that the connector is connected securely.

   1. Install the suction hose using the following procedure.

      1. Remove the vinyl tape from the suction hose, sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.

      Compressor Oil

      ND-OIL 11 or equivalent

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

      NOTE:

      Keep the O-ring and O-ring fitting surface free of foreign matter.

      3. Connect the suction hose to the compressor assembly with pulley with the bolt.

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

      NOTE:

      Make sure not to cut the O-ring while installing it. (Cut O-rings cannot be installed.)

   1. Install the No. 1 cooler refrigerant discharge hose using the following procedure.

      1. Remove the vinyl tape from the No. 1 cooler refrigerant discharge hose, and sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.

      Compressor Oil

      ND-OIL 11 or equivalent

      2. 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.

      3. Connect the No. 1 cooler refrigerant discharge hose to the compressor assembly with pulley with the bolt.

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

      NOTE:

      Make sure not to cut the O-ring while installing it. (Cut O-rings cannot be installed.)
