HEATING / AIR CONDITIONING: COMPRESSOR: INSTALLATION
1. ADJUST COMPRESSOR OIL
(a) When replacing the compressor with a new one, gradually discharge the refrigerant gas from the service valve. Then drain the following amount of oil from the new compressor before installation, so that the amount of oil contained in it is the same as that in the compressor to be replaced.

* Do not reuse the drain bolt (washer).
* New compressors are filled with sufficient oil for the whole cycle. Therefore, it is necessary to drain residual oil from the condenser and cooling unit.
Standard:
(The amount of oil inside a new cooler compressor assembly: 100 (+15) cc) - (The amount of oil remaining in the removed cooler compressor assembly A + oil remaining in the reserve chamber: 45 cc) = (The amount of oil to be removed when replacing the compressor)
NOTICE:
* When A + 45 cc exceeds the standard oil fill volume specified for the cooler compressor assembly by part number, install the compressor without adjusting the oil volume.
Example:
If A = 60 cc, A + 45 cc = 105 cc. If the standard volume is 100 cc, install the cooler compressor as is.
* When checking the compressor oil level, observe the precautions for cooler removal/ installation.
* If a new compressor is installed without removing the same amount of oil as is remaining in the vehicle pipes, the amount of oil will be too large. This prevents heat exchange in the refrigerant cycle and will cause a refrigeration failure.
* If the amount of oil remaining in the removed compressor is too low, check for an oil leak.
* Use ND-OIL8 or equivalent for compressor oil.
2. INSTALL COOLER COMPRESSOR ASSEMBLY
(a) Using an E8 "TORX" socket wrench, install the compressor with the 2 stud bolts.
Torque : 15 Nm (153 kgf-cm, 11 ft-lbf)
(b) Install the compressor with the 2 bolts and the 2 nuts.
Torque : 25 Nm (250 kgf-cm, 18 ft-lbf)

Tighten the 2 bolts and the 2 nuts in the order shown in the illustration.
(c) Connect the connector.
3. CONNECT SUCTION HOSE SUB-ASSEMBLY
(a) Remove the attached vinyl tape from the suction hose.
(b) Sufficiently apply compressor oil to a new O-ring and the fitting surface of the cooler compressor.
Compressor oil:
ND-OIL 8 or equivalent
(c) Install the O-ring onto the suction hose.
(d) Connect the suction hose to the cooler compressor with the bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
4. CONNECT DISCHARGE HOSE SUB-ASSEMBLY
(a) Remove the attached vinyl tape from the discharge hose.
(b) Sufficiently apply compressor oil to a new O-ring and the fitting surface of the cooler compressor.
Compressor oil:
ND-OIL 8 or equivalent
(c) Install the O-ring onto the discharge hose.
(d) Connect the discharge hose to the cooler compressor with the bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
(e) Install the discharge hose bracket installing bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
