Fluid, Checking Freeze Protection And Filling

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 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 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:

The Windshield Washer Concentrate G 052 164 protects the spray jets, fluid reservoir and hoses from freezing.

All vehicles with fan type spray nozzles 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 nozzles. 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 windows.

The freeze protection for the windshield washer system must assured down to approximately -13° F (-25 °C) (for arctic climates down to -31° F (-35 °C)).
