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]). 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.
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 instruc-
tions.
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 an authorized Mercedes-Benz Center.
