HEATING / AIR CONDITIONING: COMPRESSOR: INSTALLATION
1. ADJUST COMPRESSOR OIL
(a) When replacing the electric inverter compressor 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)
NOTICE:
* 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.
2. INSTALL COMPRESSOR WITH MOTOR ASSEMBLY
(a) Using an E8 "TORX" socket, temporarily install the compressor with motor assembly with the stud bolt
Torque : 10 Nm (102 kgf-cm, 7 ft-lbf)
(b) Install the compressor with motor assembly with the 2 bolts and nut.
HINT
Tighten the 2 bolts and nut in the order shown in the illustration.
Torque : 25 Nm (250 kgf-cm, 18 ft-lbf)
(c) Connect connector A and lock the green-colored lock as shown in the illustration.
CAUTION:
Wear insulated gloves when performing the following steps.
Text in Illustration
(d) Connect connector B.
3. CONNECT NO. 1 COOLER REFRIGERANT SUCTION HOSE
(a) Remove the vinyl tape from the hose.
(b) 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
(c) Install the O-ring to the No. 1 cooler refrigerant suction hose.
NOTICE:
* 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.
(d) Install the No. 1 cooler refrigerant suction hose to the compressor with motor assembly with the bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
4. CONNECT NO. 1 COOLER REFRIGERANT DISCHARGE HOSE
(a) Remove the vinyl tape from the hose.
(b) 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
(c) Install the O-ring to the No. 1 cooler refrigerant discharge hose.
NOTICE:
* 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.
(d) Install the No. 1 cooler refrigerant discharge hose to the compressor with motor assembly with the bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
5. CONNECT NO. 2 RADIATOR HOSE
(a) Using pliers, grip the claws of the clip and slide the clip to install the No. 2 radiator hose.
6. ADD COOLANT (for Engine) Coolant (for Engine)
7. INSPECT FOR COOLANT LEAK (for Engine) Cooling System
