Section 39 (Air Conditioning System (Plug-In) (Service Information)): Compressor: Installation: Installation

1. 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: 130 to 145 cc (4.4 to 4.9 fl. oz.)) - (Remaining oil amount in the removed compressor with motor assembly) = (Oil amount to be removed from the new compressor when replacing)

   NOTE:

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

1. Temporarily install the compressor with motor assembly with the 3 bolts.
2. Install the compressor with motor assembly with the 3 bolts.

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

   NOTE:

   Tighten the bolts in the order shown in the illustration to install the compressor with motor assembly.

3. Connect the connector <B>.

4. Connect the connector <A> and lock the green-colored lock as shown in the illustration.
   WARNING:

   Make sure to wear insulating gloves.

   NOTE:

   Make sure that the connector is connected securely.

1. Remove the attached vinyl tape from the 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 onto the suction hose sub-assembly.
   NOTE:

   • Keep the O-ring and O-ring fitting surfaces free from dirt or any foreign objects.
   • 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 sub-assembly onto the compressor with motor assembly with the bolt.

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

3. Install the O-ring onto the discharge hose sub-assembly.
   NOTE:

   • Keep the O-ring and O-ring fitting surfaces free from dirt or any foreign objects.
   • 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.
