- 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 using a pipette. The bright/dark boundary can be clearly recognized on the "WATERLINE".
-- Check concentration of anti-freeze additive using refractometer:T10007 A .
Scale -4- of refractometer applies to windshield cleanser concentrate:G 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 |
| -7.6/ 9.4 F (-22/-23 °C) | 1 part | 2 part |

Filling with fluid
- The windshield washer fluid reservoir must be full.
- Use only windshield washer fluid concentrate:G 052 164 all-year-round.
Windshield washer fluid concentrate:G 052 164 protects the spray nozzles, the windshield washer fluid reservoir and the hoses from freezing.
All vehicles with fan type spray jets 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.
Fill with windshield washer fluid concentrate:G 052 164 in the warmer season also. The powerful cleanser removes wax and oil deposits from the windshield.
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.
