REFRIGERANT R-134A, CAPACITY
| Model | Quantity |
|---|
| New Beetle | 700 g ± 50 g (24.7 oz ± 1.8 oz) |
Obtain R-134a refrigerant from a local A/C supplier under one of the following names
- R-134a
- Tetrafluoroethane
- CH 2 F CF 3
- H-FKW 134a
- SUVA ® TRANS A/C
- ARCTON ® 134a
Note. R-134a refrigerant is packaged in different containers. Some are used only for commercial applications which are sold in cylinders using a 1/4" flare fitting. This does not connect to the vehicle fittings and servicing equipment. Use only R-134a which come in containers having the correct type of service fitting.
REFRIGERANT OIL R134A, CAPACITIES
| Model | Total system capacity |
|---|
| New Beetle | 135 cc (4.6fl. oz.) |
Replacement A/C compressors supplied by the Parts Department are filled with 135 cc (fl. oz.) of refrigerant oil. This is the total A/C system refrigerant oil capacity.
