PROCEDURE
ADJUST COMPRESSOR OIL
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: 120 to 135 cc (4.2 to 4.8 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-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
Using an E8 "TORX" socket, temporarily install the compressor with motor assembly with the stud bolt.
Install the compressor with motor assembly with the 2 bolts and nut.
Tech Tips
Tighten the 2 bolts and nut in the order shown in the illustration.
| *1 | Green-colored Lock |
Connect the connector <B>.
Connect 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 insulated gloves.
Note
Make sure that the connector is connected securely.
CONNECT NO. 1 COOLER REFRIGERANT SUCTION HOSE
Remove the vinyl tape from the hose.
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 |
Install the O-ring to the No. 1 cooler refrigerant suction hose.
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.
Install the No. 1 cooler refrigerant suction hose to the compressor with motor assembly with the bolt.
CONNECT NO. 1 COOLER REFRIGERANT DISCHARGE HOSE
Remove the vinyl tape from the hose.
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 |
Install the O-ring to the No. 1 cooler refrigerant discharge hose.
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.
Install the No. 1 cooler refrigerant discharge hose to the compressor with motor assembly with the bolt.
