Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Refrigerant Oil Capacities: Notes
The allocation for the Zexel / Valeo, Sanden or Denso) A/C compressors can be found in the vehicle-specific repair information. Refer to Removal and Installation (vehicle-specific repair information).
Beginning the production year 2006, the name of the Zexel A/C compressor was changed from Zexel to Valeo.
With Zexel, Denso and Sanden compressors, the amount of refrigerant oil in the replacement compressor corresponds to the total quantity of oil to be added. On A/C compressor replacement, the quantity of refrigerant oil in the A/C compressor to be installed must therefore be adjusted (an incorrect refrigerant oil quantity will damage the A/C compressor).
When pouring refrigerant oil out of replacement A/C compressor (or malfunctioning A/C compressor), a small quantity of oil generally remains in the A/C compressor (20 to 30 cm3 ). This amount of refrigerant oil does not affect the function of the air conditioner and can therefore be ignored (always remains in A/C compressor).
Following initial switch-on, the refrigerant oil is distributed throughout the entire refrigerant circuit.
The specified capacities for the refrigerant oil apply if no other different specifications given for the S and RS.
Refrigerant oil capacities when replacing refrigerant circuit components refer to REMOVAL AND INSTALLATION and Removal and Installation , (vehicle-specific repair information).

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.
