Oil for refrigerant circuit
For air conditioning systems with R134a refrigerant, a special oil is used, different from that used previously.
Order oil for the refrigerant circuit by part number
| 7SEU1SC; denso company | G0E2 300 A2 |
| RXE17;sanden company | G052 154 A2 |
| Model code | Release time | Filling capacity |
| 1K0 820 859 E Denso | starting from 07.07 | 140 cm³ ±10 cm³ |
| 1K0 820 859 F Sanden | starting from 07.07 | 110 cm³ ±10 cm³ |
1) The specified amount of oil is contained in the compressor supplied as a spare part, the volume of oil corresponds to the filling capacity.
Important information: Air conditioning circuit oil intensively absorbs moisture, so containers with oil must be closed immediately after use.
Oil distribution
The oil located in the compressor crankcase before the first switching on of the air conditioning system is distributed along the circuit as follows:
- Air conditioning compressor - approximately 50%
- Capacitor - approximately 10%
- Suction pipe - approximately 10%
- Evaporator - approximately 20%
- Receiver - approximately 10%
