Refrigerant Oil: Service and Repair
Air Conditioning (A/C) System Oil Charge Replenishing
Tools Required
J 41459 A/C Oil Injector
Important: The addition of lubricating oil must be carried out whenever any component is replaced in the A/C system to compensate for
oil trapped in the removed component. Carrying out this procedure ensures the A/C system always has the correct amount of oil as
specified by the manufacturer.
1. Evacuate the A/C system for a minimum of 30 minutes and to minus 100 kPa negative gauge pressure. Refer to Refrigerant Recovery and
Recharging (See: Heating and Air Conditioning/Service and Repair/Procedures/Refrigerant Recovery and Recharging).
Important: Make sure the valve (3) is in the closed position.
2. Remove the plunger (1) from the J 41459 (2) and pour in the appropriate amount of polyalkylene glycol (PAG) oil specified for the replaced
component. Refer to Refrigerant System Capacities (See: Heating and Air Conditioning/Specifications/Capacity Specifications).
3. Jiggle the plunger (1) to remove any air in the J 41459 (2).
4. With the A/C system still evacuated, connect the J 41459 (1) to the low side charging port (2).
5. Turn the J 41459 shut off valve tap (3) to the open position to depress the low side charging port (2) schrader valve.
The oil should now be drawn into the A/C system due to the low pressure in the A/C system.
