Installation

AIR CONDITIONING: COMPRESSOR (for 2ZR-FE): INSTALLATION

1. ADJUST COMPRESSOR OIL LEVEL

(a) When replacing the cooler compressor 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:

(The amount of oil inside a new compressor: 90 (+15) cc (3 (+0.51) fl.oz.)) - (The amount of oil remaining in the removed compressor) = The amount of oil to be removed when replacing the compressor

NOTICE:
* 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 oil leakage.
* Use ND-OIL8 or equivalent for compressor oil
2. INSTALL COMPRESSOR

(a) Using a "TORX" socket wrench (E8), install the compressor with the 2 stud bolts.





Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)

(b) Install the compressor with the 2 bolts and the 2 nuts.





HINT
Tighten the bolts and the nuts in the order shown in the illustration.

Torque : 25 Nm (255 kgf-cm, 18 ft-lbf)

(c) Connect the connector and 2 clamps.





3. CONNECT NO. 1 COOLER REFRIGERANT SUCTION 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.

Compressor oil:

ND-OIL 8 or equivalent

(c) Install the O-ring onto the suction hose.

(d) Install the suction hose onto the compressor with the bolt.





Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)

4. CONNECT NO. 1 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.

Compressor oil:

ND-OIL 8 or equivalent

(c) Install the O-ring onto the discharge hose.

(d) Install the discharge hose onto the compressor with the bolt.





Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
