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 150 mL <Vehicles without
rear cooler> or 120 mL <Vehicles with rear cooler> of compressor 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.
<Vehicles without rear cooler>
Compressor oil: DH-PR
Quantity
Front Evaporator: 35 mL
Condenser: 15 mL
A/C hose and pipe: 10 mL
<Vehicles with rear cooler>
Compressor oil: ND-OIL8
Quantity
Front Evaporator: 30 mL
Rear Evaporator: 15 mL
Condenser: 25 mL
A/C hose and pipe: 15 mL
