1997 MERCEDES-BENZ ML320 coolant reservoir

307 Technical data
Fuels, coolants, lubricants etc.
Windshield washer system and headlamp cleaning system*
Both the windshield washer and headlamp
cleaning system* are supplied from the
windshield washer fluid reservoir.
The windshield and headlamp washer fluid
reservoir has a capacity of approx.
8.0 US qt (7.6 l).
Refill the reservoir with MB Windshield
Washer Concentrate “S” and water (or
concentrate and commercially avail-
able premixed windshield washer
solvent / antifreeze, depending on am-
bient temperatures).Windshield and headlamp washer fluid
mixing ratio
For temperatures above freezing, use
MB Windshield Washer Concentrate “S”
and water:

1 part “S” to 100 parts water
[40 ml “S” to 1 gallon (4 liters) water].
For temperatures below freezing, use
MB Windshield Washer Concentrate “S”
and commercially available premixed
windshield washer solvent / antifreeze:


1part “S” to 100parts solvent
[40 ml “S” to 1 gallon (4 liters) solvent].
Warning!
G
Washer solvent / antifreeze is highly flam-
mable. Do not spill washer
solvent / antifreeze on hot engine parts, be-
cause it may ignite and burn. You could be
seriously burned.

Coolant level indicator electronic switch

The coolant level indicator electronic switch

(S41) is integrated in the coolant reservoir.

Coolant level switch, taskTo record the coolant level:

Coolant level
in order
or
below minimum

Coolant level switch, design
The coolant level indicator electronic switch

(S41) consists of two electrodes which are

permanently cast to the coolant reservoir and

a connector with contacts which have an

electrical connection to the electrodes.

Coolant level switch, function
The two electrodes are either immersed or

not immersed in the coolant depending on the

coolant level. As a result the test current

changes via the coolant level indicator

electronic switch (S41). This change is

evaluated by the instrument cluster (A1).

An alternating current is used so that the

electrodes do not disintegrate.
