Take care not to spill any coolant on
painted surfaces. You could otherwise
damage the paintwork.
Coolant additive with corrosion/
antifreeze protection !
Use only approved antifreeze/corrosion
inhibitor that complies with MB
Specification for Service Products, Sheet
Number 325. Using other, non-approved
antifreeze/corrosion inhibitors may cause
damage to the coolant system and reduce
the engine's service life.
Coolant is a mixture of water and antifreeze/
corrosion inhibitor. It performs the following
tasks:
R corrosion protection
R antifreeze protection
R raises the boiling point
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection. Coolant
must be used in the system all yearr ound to
ensure anti-corrosion protection and a raised
boiling point –even in countries with high
outside temperatures.
To prevent damage to the engine cooling
system, use only approved corrosion
inhibitor/antifreeze that comply with the
Mercedes-Benz Specifications for Service
Products. You will find information about
approved corrosio ninhibitor/antifreeze for
your vehicle in the Maintenance Booklet.
We recommend corrosion inhibitor/
antifreeze tha tmeets the requirements in MB
Specifications for Service Products Sheet
Number 325.
Check the antifreeze/corrosion inhibitor
concentration in the coolant every six
months. The percentage of corrosion inhibitor/
antifreeze additive in the engine cooling
system should:
R
be at least 50%. This way, the engine
cooling system is protected against
freezing down to approximately -35 ‡
(-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
If there has been coolant loss, do not refill
only with water. If the vehicle has lost coolant,
add equal parts water and corrosion
inhibitor/antifreeze additive. The water used
as part of the coolant mixture must fulfill
certain requirements; these are usually
fulfilled by drinking water. If the water quality
is not sufficient, you must treat the water.
Further information can be obtained at any
qualified specialist workshop.
