Windshield Washer 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 concentration of anti-freeze additive using Refractometer T10007 A.
The scale -4- of the refractometer is designed specifically for Windshield Washer ConcentrateG 052 164.
Mixture Ratio:
| Freeze protection to | Windshield washer fluid concentrate 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 |
| 34.5/36.4 °F (-37/-38 °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.
The Windshield Washer ConcentrateG 052 164 protects the spray jets, fluid reservoir and hoses from freezing.

The complicated spray jet system could otherwise become blocked due to crystallized washer fluid that can affect the fan pattern of the spray nozzle. Windshield Washer Fluid Concentrate -G 052 164 assures that the nozzles remain functional even at very low temperatures.
Use Windshield Washer Fluid Concentrate -G 052 164 in the warm season as well. The powerful cleanser removes wax and oil deposits from the windows.
