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 -35°F (-37°C) and corro-
sion protection.If the antifreeze mixture is effective to 
-35°F (-37°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 corrosion 
protection and increase in the boil-over 
protection. Refer to Maintenance Booklet 
for replacement interval.
Coolant system design and coolant used 
stipulate 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 are used to 
renew the coolant concentration or bring it 
back up to the proper level. 
For information on other Mercedes-Benz 
approved products of equal specification, 
refer to the Factory Approved Service 
Products pamphlet (USA only) or contact 
an authorized Mercedes-Benz Center.To provide important corrosion protection, 
the solution must be at least 
50% anticorrosion/antifreeze (equivalent 
to freeze protection to approximately 
-35°F [-37°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 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-
tact an authorized Mercedes-Benz Center.
! Add premixed coolant solution only. Adding 
water and MB 325.0 Anticorrosion/Antifreeze 
separately from each other, could cause engine 
damage not covered by the Mercedes-Benz 
Limited Warranty.
