REFRIGERANT CHARGING.)

3. Remove the splash shield.
4. Loosen the drive belt and remove it.

Caution

• If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and 

abnormal noise will occur. Always immediately plug open fittings after removing any refrigeration 
cycle parts to keep moisture or foreign material out of the cycle.

5. Remove in the order indicated in the table. Do not 

allow compressor oil to spill.

A/C Compressor Installation Note

Caution

• Due to the high moisture-absorption characteristics of the compressor oil, it may absorb moisture 

if left over a long period of time thereby negatively affecting A/C operation. Drain the compressor 
oil and refill within 10 min. of each other.

1. Rotate new A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a clean measuring 

device. Use this refrigerant oil to refill new A/C compressor. Do not allow refrigerant oil to become 
contaminated.

2. Rotate old A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a separate, clean 

measuring device.

3. Compare those oil amounts. The amount of the oil drained from the new A/C compressor should be greater 

than the old one.

4. Pour the same amount oil of drained from the old A/C compressor back into the new A/C compressor.

A/C compressor oil type

• ATMOS GU10

A/C compressor oil sealed volume (approx. quantity)

• 120 ml {120 cc, 4.06 fl oz}

1. Disconnect the negative battery cable.
2. Discharge the refrigerant from the system. (See 07-10-6 REFRIGERANT RECOVERY.) (See 07-10-2 

REFRIGERANT CHARGING.)

3. Disconnect the body earth cable installed to No.3 engine mount rubber.
4. Disconnect the insulator. (See 07-11-2 A/C UNIT REMOVAL/INSTALLATION.)
5. Remove in the order indicated in the table. Do not allow compressor oil to spill.

Caution

• If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and 

abnormal noise will occur. Always immediately plug all open fittings after removing any 
refrigeration cycle parts to keep moisture or foreign material out of the cycle.

6. Install in the reverse order of removal.
7. Perform the refrigerant system performance test. (See 07-10-6 REFRIGERANT SYSTEM PERFORMANCE

Refrigerant Line Removal Note
Spring-lock coupling type

1. Set the SST.

2. While looking through the inspection hole of the 

SST, insert the protruding part of the SST until it 
makes contact with the cage section.

3. Use the SST to disconnect the male pipe or hose 

from the female by pulling the male pipe or hose.

Note

• The male pipe or hose can be disconnected 

easily from the female pipe by pulling from 
the male pipe or hose while maintaining the 
pressure of the protruding part of the SST.

Refrigerant Line Installation Note

1. When installing a new cooler pipe or cooler hose, add a supplemental amount of ATMOS GU10 compressor oil 

into the refrigeration cycle.

Supplemental amount (approx. quantity)
5 ml {5 cc, 0.2 fl oz}: Cooler pipe
10 ml {10 cc, 0.3 fl oz}: Cooler hose

2. Apply compressor oil to the O-rings and connect the joints.
3. Tighten the joints.
