Refilling Of Oil In The A/C System

2005 Mitsubishi Lancer L4-2.0L SOHCSECTION Refilling Of Oil In The A/C System
REFILLING OF OIL IN THE A/C SYSTEM
Too little oil will provide inadequate compressor lubrication and cause a compressor failure. Too much oil will increase discharge air temperature.

When a compressor is installed at the factory, it contains 140 cu.cm (4.7 floz) <2.0 L> or 120 cu.cm (4.0 floz) <2.4 L> of refrigerant oil. While the A/C system is in operation, the oil is carried through the entire system by the refrigerant. Some of this oil will be trapped and retained in various parts of the system. When the following system components are changed, it is necessary to add oil to the system to replace the oil being removed with the component.

Compressor oil: SUN PAG 56
Quantity:
- Evaporator: 60 cu.cm (2.0 floz)
- Condenser: 15 cu.cm (0.5 floz)
- Suction hose: 10 cu.cm (0.3 floz)
RENDER: 1.0x
