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 approx. -22°F
(-30°C)
and corrosion protection. The coolant solution must be used year round to provide the
necessary corrosion protection and increase in the boil-over protection. You should have it replaced
every 3 years. To provide the important corrosion protection, the solution must be at least 45%
anticorrosion/antifreeze (equals a 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
anticorrosion/antifreeze should be used to bring it up to the proper level (have cooling system
checked for signs of leakage). 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 dealer.
Anticorrosion/antifreeze
Your vehicle contains a number of aluminum parts. The use of aluminum components in motor
vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifically
formulated to protect the aluminum parts. (Failure to use such anticorrosion/antifreeze coolant will
result in a significantly shortened service life.)
Therefore the following product is strongly recommended for use in your car: Mercedes-Benz
Anticorrosion/Antifreeze Agent. Before the start of the winter season (or once a year in the hot
southern regions), you should have the anticorrosion/antifreeze concentration checked. The coolant is
also regularly checked each time you bring your vehicle to your authorized Mercedes-Benz dealer for
service.
