Refrigerant Oil Capacities In Refrigerant Circuits For Refrigerant R1234YF
Depending on the time period of production and the engine, the compressor construction type may vary. Refer to the Parts Information.
Depending on the A/C compressor type, different refrigerant oil capacities may be designated for the refrigerant circuit. Refer to the MAINTENANCE, DIAGNOSIS (2016 FLUID CAPACITY TABLES) [COUPE] / MAINTENANCE, DIAGNOSIS (2017 - 2018 FLUID CAPACITY TABLES) [COUPE] / MAINTENANCE, DIAGNOSIS (FLUID CAPACITY TABLES) (1 OF 2) [COUPE] / MAINTENANCE, DIAGNOSIS (FLUID CAPACITY TABLES) (2 OF 2) [COUPE] .
There are different refrigerant oils used for the "Denso" -, "Delphi/Mahle" -, "Visteon" and "Sanden" A/C compressors. Refer to APPROVED REFRIGERANT OILS FOR REFRIGERANT R1234YF and the Parts Information.
For additional information about refrigerant oil, refer to REFRIGERANT AND REFRIGERANT OIL .

The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. If the A/C compressor is replaced, the amount of oil in the A/C compressor must then be adjusted. Refer to COMPONENTS, REPLACING ..
At the start of production, mechanically-driven A/C compressors from different manufacturers are installed on all vehicles. Refer to the Parts Information.
These A/C compressors are available as replacement parts with different oil fill capacities, therefore note capacity on the A/C compressor and the exact part number. Refer to the Parts Information
The reason for the different oil capacities inside the A/C compressor is due to the design of the A/C compressor (with or with an oil separator on the high pressure connection) or to the design of the refrigerant circuit if the A/C compressors are have the identical design. Pay attention to the different capacities. Too much oil in the circuit leads to higher pressures and reduces cooling output of the system. Too little oil may lead to lubrication problems in the compressor.
A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.
