Windshield and Headlamp Washer System, Checking
Fluid, Checking Freeze Protection and Filling
Special tools, testers and auxiliary items required
• Refractometer (T10007)
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 (T10007 ).
Scale - 1 - of refractometer applies to Windshield Cleanser Concentrate (G 052 164).
The scale - 2 - is designed for commercially available windshield cleanser as well as a mixture of commercially available windshield cleanser and Windshield Cleanser Concentrate (G 052 164 ).
Mixture Ratio
Filling
The windshield wash/wipe system fluid reservoir must be filled up fully.
Use only Windshield Cleanser Concentrate (G 052 164) all-year-round when topping-off the windshield wash/wipe system.
• Windshield Cleanser Concentrate (G 052 164) protects the spray nozzles, fluid reservoir and hoses from freezing.
• All vehicles with fan type spray nozzles must be filled with Windshield Cleanser Concentrate (G 052 164) as this fluid has a low viscosity at minus temperatures. The complicated spray nozzle system could otherwise become blocked due to crystallized washer fluid that can affect the fan pattern of the spray nozzle. Windshield Cleanser Concentrate (G 052 164) assures that the fan type spray nozzles remain functional even at low temperatures.
• Fill with Windshield Cleanser Concentrate (G 052 164) in the warmer season also. 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.
Windshield Wiper/Washer Nozzles, Checking and Adjusting Washer
Special tools, testers and auxiliary items required
• Adjustment Tool (T10127) equipped with needle 3125/ 5 A
• In cases where contamination in spray nozzle results in an uneven spray pattern, remove the spray jet and rinse it with water in the opposite direction of the spray flow. Subsequently blowing through in the opposite direction of the spray flow with compressed air is permitted. Do not use any objects to clean the spray nozzles!
Windshield
The washer nozzles are preset. Small height adjustments can be made.
- If both spray fields are not at same height, adjust spray direction upward or downward as follows:
1 Cowl plate in front of front window
2 Adjuster
3 Fan-type nozzle
4 Hood
- Adjust spray nozzle - 3 - by rotating at adjuster - 2 - using a screwdriver.
• "Clockwise" deeper adjustment.
• "Counterclockwise" higher adjustment.
Rear Window
- Adjust nozzle with (T10127) so that fluid sprays onto upper third of rear window, as shown.
Headlamp Washer Nozzles
Special tools, testers and auxiliary items required
• (T10167)
Nozzle setting dimensions for right headlamp (left headlamp is arranged symmetrically)
Check Spray Nozzles Setting
- Switch on driving lights.
- Operate windshield washer system for front window.
Headlamps are washed when windshield washer lever is held in " wipe position" at least 1.5 seconds.
Spray pattern should encounter headlight lamps at center, see - B - and - C -.
Adjusting Nozzles
- Switch on driving lights.
- Operate windshield washer system for front window.
Headlamps are washed when windshield washer lever is held in " wipe position" at least 1.5 seconds.
Spray nozzles - arrow - are driven outward.
- Perform the following work procedure:
- Align the nozzle spray direction with the (T10167) at the upper edge of the headlamp, - B - and - C -.
• In cases where contamination in spray nozzle results in an uneven spray pattern, remove the spray nozzle and rinse it with water in the opposite direction of the spray flow. Subsequently blowing through in the opposite direction of the spray flow with compressed air is permitted. Do not use any objects to clean the spray nozzles!
