2004 MERCEDES-BENZ C240 4MATIC WAGON coolant

351 Technical data
Fuels, coolants, lubricants, etc.
When switching fuels, make sure:

Fuel level is below half full.


Fuel level is above reserve (fuel reserve
warning lamp is not lit).


Amount of added fuel is more than
5 gallons (20 liters).


Ignition is off during refill.


Immediately after refueling engine is
started and operated for at least five
minutes.
These precautions and recommendations
are supposed to prevent any difficulties
when starting and operating the engine
which otherwise may be experienced
before the engine has fully adapted to the
different fuel.
If in spite of these recommendations the
engine does not perform properly, adding
more gasoline [at least 3 gallons
(12 liters)] to the fuel may improve the
engine behavior.Cold weather performance
It is possible that starting times will signif-
icantly increase at temperatures
below 32°F (0°C). At low temperatures
the use of a block heater (Canada only) is
recommended (see your authorized
Mercedes-Benz Center for further
information). Rough idling may also be
experienced at such temperatures before
the engine is fully warmed up.
Hot weather performance
At ambient temperatures above 95°F
(35°C) start times may increase and be
accompanied by a rough idle following the
start.Cruising range
E85 fuel contains less energy per gallon
than gasoline. To ensure that engine per-
formance with ethanol fuel is similar to
that when using gasoline, the engine must
burn more ethanol fuel. As a result, it is to
be expected that the fuel consumption will
increase when using E85 compared to
gasoline operation.
Maintenance
Please inform your Mercedes-Benz Center
if you use or have used E85 fuel when your
vehicle is delivered for maintenance or
repairs.
!E85 fuel is unsuitable for use when
ambient temperatures fall below 14°F
(-10°C).
iUse of E85 may reduce your driving
range.

352 Technical dataFuels, coolants, lubricants, etc.Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which
provides:

Corrosion protection


Freeze protection


Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and
corrosion protection.
If the antifreeze mixture is effective
to -22°F (-30°C), the boiling point of the
coolant in the pressurized cooling system
is reached at approx. 266°F (130°C).The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil-over
protection. Refer to Service Booklet for
replacement interval.
Coolant system design and coolant used
stipulate the replacement interval. The
replacement interval published in the Ser-
vice Booklet is only applicable if MB 325.0
anticorrosion/antifreeze solution or other
Mercedes-Benz approved products of
equal specification (see Factory Approved
Service Products pamphlet) are used to re-
new the coolant concentration or bring it
back up to the proper level.
To provide important corrosion protection,
the solution must be at least 45%
anticorrosion/antifreeze [equivalent to
freeze protection to approx. - 22°F
(-30°C)]. If you use a solution that is more than 55%
anticorrosion/antifreeze [freeze
protection 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 the mixture is
in accordance with label instructions.
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,
consult your authorized Mercedes-Benz
Center.

353 Technical data
Fuels, coolants, lubricants, etc.
Anticorrosion/antifreeze
Your vehicle contains a number of
aluminum parts. The use of aluminum
components in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifi-
cally formulated to protect the aluminum
parts.Failure to use such anticorrosion/anti-
freeze coolant will result in a significantly
shortened service life.
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0
Anticorrosion/Antifreeze 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.

354 Technical dataFuels, coolants, lubricants, etc.Windshield washer and headlamp cleaning* 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.:

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


6.4 US qt (6.0 l) in vehicles with
headlamp cleaning system*

Refill the reservoir with MB Windshield
Washer Concentrate and water
(or concentrate and commercially
available premixed windshield washer
solvent/antifreeze, depending on
ambient temperatures).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 (4.0 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 (4.0 liters) solvent].
Warning!
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze
on hot engine parts, because it may ignite
and burn. You could be seriously burned.
