Kia Optima: Compressor Oil. Repair procedures
Oil Specification
| 1. |
The HFC-134a system requires
synthetic (PAG) compressor oil whereas the R-12 system requires mineral
compressor oil. The two oils must never be mixed. |
| 2. |
Compressor (PAG) oil varies according
to compressor model. Be sure to use oil specified for the model of compressor. |
Handling of Oil
| 1. |
The oil should be free from moisture,
dust, metal powder, etc. |
| 2. |
Do not mix with other oil. |
| 3. |
The water content in the oil
increases when exposed to the air. After use, seal oil from air immediately.
(HFC-134a Compressor Oil absorbs moisture very easily.) |
| 4. |
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 Return Operation
There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculation 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 "ON" and set the blower motor 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. |
