440 Technical data
Fuels, coolants, lubricants, etc.
The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil-over
protection. Refer to Maintenance Booklet
for replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance 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 renew 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 an authorized Mercedes-Benz
Center.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 an authorized Mercedes-Benz
Center for service.

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.
