Kia Forte: Compressor Oil Specification
Second generation YD (2014-2018) / Kia Forte TD 2014-2018 Service Manual / Heating,Ventilation, Air Conditioning / Air Conditioning System / Compressor Oil Specification
| 1. |
The R-134a system requires synthetic compressor oil (PAG) whereas
the R-12 system requires mineral compressor oil. The two oils must never
be mixed.
|
| 2. |
Compressor oil (PAG) 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. (R-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 total volume in system
PAG OIL (FD46XG)
- R-134a : 110 ± 10cc

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 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.
|
| 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 (1.70 fl.oz) |
| Condenser |
30 cc (1.02 fl.oz) |
| Receiver-drier |
30 cc (1.02 fl.oz) |
| Refrigerant line (One piece) |
10 cc (0.34 fl.oz) |
For compressor replacement, subtract the volume of oil drained from the
removed compressor from the specified volume, and drain the calculated volume
of oil from the new compressor:
The specified volume - volume of removed compressor = volume to drain
from the new compressor.
Even if no oil is drained from the removed compressor, don’t drain
more than 50cc from the new compressor.
