HEATING / AIR CONDITIONING: COMPRESSOR (for 1AR-FE): INSTALLATION
1. ADJUST COMPRESSOR OIL LEVEL
(a) When replacing the cooler compressor assembly with a new one, gradually discharge the inert gas (helium) from the service valve, and drain the following amount of oil from the vents indicated by the arrows in the illustration before installation.
HINT
The drain bolt and washer can be reused.
Standard:
(Oil capacity inside the new compressor assembly with pulley: 130 + 15 cc (4.4 + 0.51 fl.oz.) ) - (Remaining oil amount in the removed compressor assembly with pulley) = (Oil amount to be removed from the new compressor when replacing)
NOTICE:
* If a new compressor is installed without removing some oil remaining in the pipes of the vehicle, the oil amount will be excessive. This prevents heat exchange in the refrigerant cycle and causes refrigeration system failure.
* If the volume of oil remaining in the removed compressor is too small, check for oil leaks.
* Be sure to use ND-OIL 8 or equivalent for compressor oil.
2. INSTALL COMPRESSOR ASSEMBLY WITH PULLEY
(a) Using "TORX" socket wrench E8, install the 2 stud bolts.
Torque : 10 Nm (102 kgf-cm, 7 ft-lbf)
(b) Install the the 2 bolts and 2 nuts to the compressor assembly with pulley.
Torque : 25 Nm (255 kgf-cm, 18 ft-lbf)
NOTICE:
Tighten the bolts and nuts in the order shown in the illustration to install the compressor assembly with pulley.
3. CONNECT SUCTION HOSE SUB-ASSEMBLY
(a) Remove the attached vinyl tape from the hose.
(b) Apply sufficient compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.
Compressor oil:
ND-OIL 8 or equivalent
(c) Install the O-ring onto the suction hose sub-assembly.
NOTICE:
Keep the O-ring and O-ring fitting surfaces free from dirt or any foreign objects.
(d) Install the suction hose sub-assembly onto the compressor assembly with pulley with the bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
4. CONNECT COOLER REFRIGERANT DISCHARGE HOSE
(a) Remove the attached vinyl tape from the hose.
(b) Apply sufficient compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.
Compressor oil:
ND-OIL 8 or equivalent
(c) Install the O-ring onto the discharge hose.
NOTICE:
Keep the O-ring and O-ring fitting surfaces free from dirt or any foreign objects.
(d) Install the cooler refrigerant discharge hose onto the compressor assembly with pulley with the bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
(e) Using pliers, grip the claws of the clip and slide the clip to install the No. 2 radiator hose.
(f) Engage each clamp.
(g) Connect each connector.
