Fluid, Checking Freeze Protection And Filling
Special tools and workshop equipment required
- Refractometer T10007 A
Read the bright/ark boundary to obtain an accurate reading for the following tests. Place a drop of water on the glass to improve the readability of the bright/dark boundary. The bright/dark boundary can be clearly recognized on the "WATERLINE".
-- Check the concentration of anti-freeze additive using a refractometer T10007 A.
Scale -4- of refractometer applies to windshield cleanser concentrate G 052 164.

Mixture Ratio
| Freeze protection to | Windshield Washer fluid G 052 164 | Water |
|---|---|---|
| 1.4/-0.4 °F (-17/-18 °C) | 1 part | 3 part |
| 7.5/9.5 °F (-22/-23 °C) | 1 part | 2 part |
| 34.5/36.5 °F (-37/-18 °C) | 1 part | 1 part |
Filling-up with fluid:
The windshield washer system fluid reservoir must be filled.
Use only windshield washer fluid concentrate G 052 164 all-year-round.
NOTE:
- Windshield washer fluid concentrate G 052 164 protects the spray nozzles, the reservoir and the hoses from freezing.
- All vehicles with fan type spray nozzle must be filled with windshield washer fluid concentrate G 052 164 as this fluid has a low viscosity at minus temperatures. The complicated spray jet system could otherwise become blocked due to crystallized washer fluid that can affect the fan pattern of the spray jet. Windshield washer fluid concentrate G 052 164 assures that the fan type spray nozzles remain functional even at low temperatures.
- Use windshield washer concentrate G 052 164 in the warmer periods of the year also. The powerful cleanser removes wax and oil deposits from the windows.
- Freeze protection (anti-freeze) must be guaranteed to approximately -13 °F(-25 °C) (approximately -31 °F (-35 °C) in countries with an arctic climate) in the washer system.
