Fuels, coolants, lubricants etc.
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).
The coolant solution must be used 
year-round to provide the necessary corro-
sion protection and increase boil-over pro-
tection. 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 solu-
tion 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. 
To provide important corrosion protection, 
the solution must be at least 45% anticor-
rosion/antifreeze [equivalent to freeze 
protection to approximately - 22°F 
(-30°C)]. If you use a solution that is more 
than 55% anticorrosion/antifreeze [freeze 
protection to approximately - 49°F 
(-45°C)], the engine temperature will in-
crease due to the lower heat transfer capa-
bility of the solution. Therefore, do not use 
more than this amount of anticorro-
sion/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, con-
sult your authorized Mercedes-Benz 
Center.
Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines 
necessitates that anticorrosion/antifreeze 
coolant used in such engines be specifical-
ly formulated to protect the aluminum 
parts. (Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life.)
