Coolants
The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil-over pro-
tection. You should have it replaced every
15 years or 150000 miles (250000 km),
whichever comes first. Coolant system
design and coolant used stipulate the
replacement interval. The above replace-
ment interval is only applicable if
MB 325.0 anticorrosion/antifreeze
solution or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products pam-
phlet) are used to renew the coolant con-
centration or bring it back up to the proper
level.
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.
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which pro-

Corrosion protection
Freeze protection
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.
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 corro-
sion protection.
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.
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 approximately 266°F
(130°C).
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)].
