Windshield Washer Fluid, Checking Freeze Protection And Filling
Warning information for the high voltage system:
For procedures where the ignition must be switched off, refer to PROCEDURES FOR WHICH THE IGNITION NEEDS TO BE SWITCHED OFF .
Special Tools And Workshop Equipment Required
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 the 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° F / -0.4° F (-17/-18 °C) | 1 part | 3 part |
| -7.6° F / -9.4° F (-22/-23 °C) | 1 part | 2 part |
| -34.6° F / -36.4° F (-37/-38 °C) | 1 part | 1 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 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 concentrate:G 052 164 in the warmer periods of the year 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.
