Refrigerant Oil: Service and Repair
COMPRESSOR OIL
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 150cc (5.07 fl.oz)
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 "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.
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.
NOTE: Even if no oil is drained from the removed compressor, don't drain more than 50cc from new compressor.
