Mercedes Benz 2003 e 320 Benutzerhandbuch

If the coolant level is low, water and MB 
Anticorrosion/Antifreeze should be used 
to bring it up to the proper level (have cool-
ing 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, con-
sult your authorized Mercedes-Benz 
Center.

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.)

Therefore, the following product is strongly 
recommended for use in your vehicle: 
Mercedes-Benz 325.0 Anticorrosion/Anti-
freeze Agent.

Before the start of the winter season (or 
once a year in 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 
Center for service.
