PROCEDURE
ADJUST COMPRESSOR OIL
When replacing the cooler compressor with a new one, gradually discharge the refrigerant gas from the service valve, and drain the following amount of oil from the new cooler compressor before installation.
| Standard |
|---|
| for Single Air Conditioning System: |
| (The amount of oil inside a new cooler compressor: 120 to 135 cc (4.1 to 4.6 fl. oz.)) - (The amount of oil remaining in the removed cooler compressor) = (The amount of oil to be removed when replacing the compressor) |
| Standard |
|---|
| for Dual Air Conditioning System: |
| (The amount of oil inside a new cooler compressor: 180 to 195 cc (6.1 to 6.6 fl. oz.)) - (The amount of oil remaining in the removed cooler compressor) = (The amount of oil to be removed when replacing the compressor) |
Note
When checking the compressor oil level, follow the A/C system precautions.
If a new cooler compressor is installed without removing some oil remaining in the pipes of the vehicle, the oil amount will be too large. This prevents heat exchange in the refrigerant cycle and causes refrigerant failure.
If the volume of oil remaining in the removed cooler compressor is too small, check for oil leakage.
for HFC-134a(R134a): Make sure to use ND-OIL 8 or equivalent compressor oil.
for HFO-1234yf(R1234yf): Make sure to use ND-OIL 12 or equivalent compressor oil.
INSTALL COOLER COMPRESSOR ASSEMBLY
Install the stud bolt.
Temporarily install the cooler compressor assembly with the 3 bolts and nut.
Tighten the 3 bolts and nut in the sequence shown in the illustration.
Connect the connector.
CONNECT SUCTION HOSE SUB-ASSEMBLY
Remove the attached vinyl tape from the hose.
Sufficiently apply compressor oil to a new O-ring and the fitting surface of the cooler compressor.
| Refrigerant | Compressor Oil |
|---|---|
| HFC-134a (R134a) | ND-OIL 8 or equivalent |
| HFO-1234yf (R1234yf) | ND-OIL 12 or equivalent |
Install the O-ring to the suction hose.
| *A | for Type A |
| *B | for Type B |
Connect the suction hose to the cooler compressor with the 2 bolts.
CONNECT DISCHARGE HOSE SUB-ASSEMBLY
Remove the attached vinyl tape from the hose.
Sufficiently apply compressor oil to a new O-ring and the fitting surface of the cooler compressor.
| Refrigerant | Compressor Oil |
|---|---|
| HFC-134a (R134a) | ND-OIL 8 or equivalent |
| HFO-1234yf (R1234yf) | ND-OIL 12 or equivalent |
Install the O-ring to the discharge hose.
Connect the discharge hose to the cooler compressor with the bolt.
