HEATING / AIR CONDITIONING: COMPRESSOR: INSTALLATION; 2013 MY FR-S [03/2012 -]

1. ADJUST COMPRESSOR OIL LEVEL

(a) 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:

Drain oil from the new compressor assembly, and then add new oil so that the amount of oil in the new compressor assembly is the same as that in the compressor assembly to be replaced.





HINT
The drain bolt and washer can be reused.

NOTICE:
* When checking the compressor oil level, observe the precautions on the cooler removal/installation.
* 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 WITH MAGNET CLUTCH

(a) Install the compressor with magnet clutch with the 3 bolts.





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

Torque : 36 Nm (367 kgf-cm, 27 ft-lbf)

(b) Connect the connector.

3. 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 with magnet clutch.

for HFC-134a (R134a)
ND-OIL 8 or equivalent

(c) Install the O-ring onto the No. 1 cooler refrigerant discharge hose.

(d) Install the No. 1 cooler refrigerant discharge hose onto the compressor with magnet clutch with the bolt.

Torque : 10 Nm (102 kgf-cm, 7 ft-lbf)

4. 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 with magnet clutch.

Compressor oil:

for HFC-134a (R134a)
ND-OIL 8 or equivalent

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

(d) Install the suction hose sub-assembly onto the compressor with magnet clutch with the bolt.
