• Refractometer (T10007)
Read the bright/dark 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 refractometer (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-up with fluid:
The windshield wash/wipe system fluid reservoir must be filled up fully.
Use only windshield cleanser concentrate (G 052 164) all-year-round when filling 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 jets must be filled with windshield cleanser 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 and adversely affect the fan pattern of the spray jet. Windshield cleanser concentrate (G 052 164) assures that the fan type spray jets 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 approx. -13 °F (-25 °C) (approx. -31 °F (-35 °C) in countries with an arctic climate) in the washer system.
Windshield Washer System, Spray Nozzle Adjustment, Checking and Adjusting
Special tools, testers and auxiliary items required
• Adjustment tool (T10127) equipped with needle 3125/ 5 A
• In cases where contamination in spray jet 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 jets!
Front window spray nozzle adjustment:
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 washer nozzle adjustment
- Adjust nozzle with adjustment tool (T10127) so that fluid sprays onto upper third of rear window, as shown.
Headlamp Washer System, Spray Nozzle Adjustment, Checking and Adjusting
Special tools, testers and auxiliary items required
• Adjustment device (T10167)
Nozzle setting dimensions for right headlamp (left headlamp is arranged similar)
Check spray nozzle 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 headlamp 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:
- Direct the spray direction of respective nozzle using adjustment tool (T10167) or adjustment tool (3019A) at upper edge of headlamp, - B - and - C -.
• In cases where contamination in spray jet 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 jets!
