Refrigerant Oil: Service and Repair
Component Refrigerant Oil Level Check
A/C Component Referigerant Oil Capacities
When an air conditioning system is first assembled at the factory, all components (except the A/C compressor) are refrigerant oil free. After the
refrigerant system has been charged with (R-134a) refrigerant and operated, the oil in the A/C compressor is dispersed through the lines and components.
The A/C evaporator, A/C condenser, and accumulator will retain a significant amount of oil. Refer to the A/C Component Refrigerant Oil Capacities
table. When a component is replaced, the specified amount of refrigerant oil must be added. When a new A/C compressor is being installed, drain the
lubricant from the used compressor, measure the amount drained and discard the used lubricant. Drain the lubricant from the new A/C compressor into a
clean container. Return the amount of lubricant measured from the used compressor, plus the amount reclaimed from the system back into the new A/C
compressor. When a line or component has ruptured and oil has escaped, the accumulator must be replaced along with the ruptured component.
