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 specifi-
cally formulated to protect the aluminum
parts.Failure to use such anticorrosion/anti-
freeze coolant will result in a significantly
shortened service life.
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0
Anticorrosion/Antifreeze 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.
