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 limit is now clearly recognizable on the "WATERLINE".
-- Check the concentration of anti-freeze additive using a Refractometer T10007 A.
The scale -4- of the refractometer is designed specifically for Windshield Washer 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 |
| 7.5/9.5°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 washer system reservoir must be filled.
Use only Windshield Washer Fluid Concentrate G 052 164 all-year-round.
The Windshield Washer Fluid Concentrate G 052 164 protects the spray jets, asher system reservoir and hoses from freezing.
All vehicles with fan type spray jets must be filled with Windshield Washer Fluid Concentrate G 052 164 because this fluid has a low viscosity at negative 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 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.
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.
