⁽¹⁾

The mechanically driven replacement compressor is already filled with a specific amount of refrigerant oil (currently 110 +/ - 10 cm depending on the A/C compressor), this refrigerant oil quantity corresponds to the oil quantity designated for this refrigerant circuit on vehicles with one evaporator. On vehicles with two evaporators, a larger refrigerant oil quantity is required in the refrigerant circuit (currently an additional 30 cm ) because of the longer refrigerant lines and the second evaporator. If the compressor is replaced after cleaning the refrigerant circuit, this refrigerant oil quantity must therefore be added to the refrigerant circuit (for example, into opened lines or component connections) in vehicles with two evaporators. If A/C compressor is replaced without having to clean the refrigerant circuit, the refrigerant oil quantity in the new A/C compressor to be installed must be adjusted to the oil quantity poured out of the old A/C compressor. Refer to Refrigerant Circuit Components, Replacing or COMPONENTS, REPLACING .

These A/C compressors are available as replacement parts with different oil fill capacities, therefore pay attention to the exact part number. Refer to the appropriate Electronic Parts Information.
A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.
