Compressor Oil
Oil Specification

The HFC-134a system requires a synthetic (PAG)
compressor oil whereas the R-12 system requires a
mineral compressor oil. The two oils must never be
mixed.

Compressor (PAG) oil varies according to
compressor model. Be sure to use oil specified for the
model of compressor.

Always use HFC-134a Vane Rotary Type
Compressor Oil (AIPDN Part No.2-90188-301-0)
Handling of Oil

The oil should be free from moisture, dust, metal
powder, etc.

Do not mix with other oil.

The water content in the oil increases when exposed
to the air. After use, seal oil from air immediately.
(HFC-134a Vane Rotary Compressor Oil absorbs
moisture very easily.)

The compressor oil must be stored in steel
containers, not in plastic containers.
Compressor Oil Check
The oil used to lubricate the compressor is circulating with
the refrigerant.
Whenever replacing any component of the system or a
large amount of gas leakage occurs, add oil to maintain
the original amount of oil.
Oil Capacity
Capacity total in system: 150cc (5.0 fl.oz)
Compressor (Service parts) charging amount:
150 cc (5.0 fl.oz)
Checking and Adjusting Oil Quantity
for Used Compressor
1. Perform oil return operation. Refer to Oil Return
Operation in this section.
2. Discharge and recover refrigerant and remove the
compressor.
3. Drain the compressor oil and measure the extracted
oil with a measuring cylinder.
4. If the amount of oil drained is much less than 90 cc
(3.0 fl. oz.), some refrigerant may have leaked out.
Conduct a leak tests on the connections of each
system, and if necessary, repair or replace faulty
parts.
5. Check the compressor oil contamination. (Refer to
Contamination of Compressor Oil in this section.)
6. Adjust the oil level following the next procedure
below.(Charging Amount)
(Collected Amount)
more than 90cc (3.0
fl.oz)same as collected
amount
less than 90 cc (3.0 fl.oz)90cc (3.0 fl.oz)
7. Install the compressor, then evacuate, charge and
perform the oil return operation.
8. Check system operation.
When it is impossible to preform oil return operation,
the compressor oil should be checked in the
following order:
1. Discharge and recover refrigerant and remove the
compressor.
2. Drain the compressor oil and measure the extracted
oil with a measuring cylinder.
3. Check the oil for contamination.
4. If more than 90 cc (3.0 fl. oz.) of oil is extracted from
the compressor, supply the same amount of oil to the
compressor to be installed.
5. If the amount of oil extracted is less than 90 cc (3.0 fl.
oz.), recheck the compressor oil in the following
order.
6. Supply 90 cc (3.0 fl. oz.) of oil to the compressor and
install it onto the vehicle.
7. Evacuate and recharge with the proper amount of
refrigerant.
8. Perform the oil return operation.
9. Remove the compressor and recheck the amount of
oil.
10. Adjust the compressor oil, if necessary.

Checking and Adjusting for
Compressor Replacement
150 cc (5.0 fl.oz.) of oil is charged in compressor (service
parts). So it is necessary to drain the proper amount of oil
from the new compressor.
1. Perform oil return operation.
2. Discharge and recover the refrigerant and remove the
compressor.
3. Drain the compressor oil and measure the extracted
oil.
4. Check the compressor oil for contamination.
5. Adjust the oil level as required.
(Amount of oil drained
from used compressor)
(Draining amount of oil
from new compressor)
less than 90 cc (3.0 fl.oz)Same as drained
amount
more than 90 cc (3.0
fl.oz)90 cc (3.0 fl.oz)
6. Evacuate, charge and perform the oil return
operation.
7. Check the system operation.
Contamination of Compressor Oil
Unlike engine oil, no cleaning agent is added to the
compressor oil. Even if the compressor runs for a long
period of time (approximately one season), the oil never
becomes contaminated as long as there is nothing wrong
with the compressor or its method of use.
Inspect the extracted oil for any of the following
conditions:

The capacity of the oil has increased.

The oil has changed to red.

Foreign substances, metal powder, etc., are present
in the oil.
If any of these conditions exists, the compressor oil
is contaminated. Whenever contaminated
compressor oil is discovered, the receiver/drier must
be replaced.
Oil Return Operation
There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculates with
the refrigerant in the system. When checking the amount
of oil in the system, or replacing any component of the
system, the compressor must be run in advance for oil
return operation. The procedure is as follows:
1. Open all the doors and the engine hood.
2. Start the engine and air conditioning switch to ªONº
and set the fan control knob at its highest position.
3. Run the compressor for more than 20 minutes
between 800 and 1,000 rpm in order to operate the
system.
4. Stop the engine.
Replacement of Component Parts
When replacing the system component parts, supply the
following amount of oil to the component parts to be
installed.
(Component parts to be
installed)
(Amount of Oil)
Evaporator 50 cc (1.7 fl. oz.)
Condenser30 cc (1.0 fl. oz.)
Receiver/dryer30 cc (1.0 fl. oz.)
Refrigerant line (one
piece)10 cc (0.3 fl. oz.)
