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 
Service 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 your authorized Mercedes-Benz 
Center.
