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)

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
