1Use MB Windshield Washer Concentrate “S” and water for temperatures above freezing or MB Windshield Washer Concentrate “S” and commercially available pre-
mixed windshield washer solvent/antifreeze for temperatures below freezing. Follow suggested mixing ratios (
page 324).

322 Technical dataFuels, coolants, lubricants etc.Coolant system design and coolant used
stipulate the replacement interval. The
above replacement interval is only applica-
ble if MB 325.0 anticorrosion/antifreeze
solution or other Mercedes-Benz approved
products of equal specification (see Facto-
ry Approved Service Products pamphlet)
are used to renew the coolant concentra-
tion or bring it back up to the proper level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. - 22°F [-30°C]). If
you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protec-
tion to approx. - 49°F [-45°C]), the engine
temperature will increase due to the lower
heat transfer capability of the solution.
Therefore, do not use more than this
amount of anticorrosion/antifreeze.If the coolant level is low, water and
MB 325.0 anticorrosion/antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure that the mix-
ture is in accordance with label instruc-
tions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult your authorized Mercedes-Benz
Center.
Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum
parts. (Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life.)
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0 Anticorrosion/Anti-
freeze agent.
Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to your authorized Mercedes-Benz
Center for service.

324 Technical dataFuels, coolants, lubricants etc.Windshield and headlamp washer system
Both the windshield and headlamp washer
systems are supplied from the windshield
washer fluid reservoir.
The washer fluid reservoir has a capacity of
approx.

6.4 US qt (6.0 l) in vehicles with head-
lamp cleaning system*


3.2 US qt (3.0 l) in vehicles without
headlamp cleaning system

Refill the reservoir with MB Windshield
Washer Concentrate and water (or con-
centrate and commercially available
premixed windshield washer sol-
vent/antifreeze, depending on ambient
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:


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