Coolant
Important safety notes The coolan
tisamixture of water and anti-
freeze/corrosio ninhibitor. It performs the
following tasks:
R anti-corrosio nprotection
R antifreeze protection
R raising th eboiling point
i When the vehicle is first delivered, it is fil-
led with acoolant mixtur ethat ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. The
engin ecould otherwise be damaged.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Servic eProducts ,MB
Approval 310.1 ,e.g. on the Internet at
http ://bevo.mercedes-benz.com .You can
also consult aMercedes-Benz Service
Centre.
! Alway suseasuitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
If antifreeze/corrosio ninhibitor is present in
the correc tconcentration, the boilin gpoint of
the coolant during operation will be around
13 0†.
The antifreeze/ corrosion inhibitor con centra-
tion in the engine cooling system should:
R be at leas t50%. This wil lprotect the engine
coolin gsystem agains tfreezin gdown to
around -3 7†.
R not excee d55% (antifreeze protection
down to -45 †);otherwise, heat will not be
dissipated as effectively.
If the vehicle has los tcoolant, top it up with
equal amount sofwater and antifreeze/cor- rosion inhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibitor
which has been approved for Mercedes-Benz.
! The engin ecoolin gsystem is filled with
coolant that must be renewed after 15
years, or after 250,000 km at the lates t. Vehicl
