Technical data
Fuels, coolants, lubricants etc.
Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.
The coolant solution must be used year
round to provide the necessary corrosion
protection and increase in boil-over pro-
tection. Refer to Service Booklet for
replacement interval.
If the coolant level is low, water and MB
anticorrosion/antifreeze should be used
to bring it up to the proper level (have cool-
ing system checked for signs of leakage).
Please make sure the mixture is in accor-
dance with label instructions.
Coolants
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 so-
lution. Therefore, do not use more than
this amount of anticorrosion/antifreeze.
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 Light
Truck Center.
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-

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 -35°F (-37°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
