Coolants
The engine coolant is a m ixture 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 —30° C ( — 22° F) and
corrosion protection. The red area of
the tem perature gauge is m atched to
the heating properties of this coolant
solution.
The coolant solution m ust 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 im portant corrosion
protection, the solution m ust be at
least 33 % anticorrosion/antifreeze
(equals a freeze protection to
— 20° C [ — 4° F]). If you use a solu
tion that is more than 55 °/o antico rro
sion/antifreeze (freeze p rotection to
— 45° C [ — 49° F]), the engine te m
perature will increase due to the lower
heat transfer capability of the solu
tion. Therefore, do not use more than
this am ount of an tico rro sio n /a n ti
freeze.
If the coolant level is low, w ater and
MB anticorro sio n /a n tifre e ze should
be used to bring it up to the proper
level (have cooling system checked
fo r signs of leakage).
The w ater in the cooling system m ust
meet minim um requirem ents, which
are usually satisfied by normal drink
ing water. If you are not sure about
the w ater quality, consult your author
ized MERCEDES-BENZ dealer.
A n ticorrosion/antifreeze
Y our vehicle contains a num ber of
aluminium parts. The use of alumin
ium co m ponents in m otor vehicle
engines necessitates that a n tico rro
s io n /a n tifre e ze /co o la n t used in such
engines be specifically form ulated to
pro te ct the aluminium parts.
(Failure to use such a n tico rro sio n /
antifreeze/coolant will result in a sig
nificantly shortened service life.)
Therefore the follow ing product, is
strongly recom m ended fo r use in
your car: MERCEDES-BENZ A n tico r
ro sion/A ntifreeze Agent.
Before the start of the w inter season
(or once a year in the hot southern
regions), you should have the anticor
rosion/antifreeze concentration
checked. The coolant is also regularly
checked each tim e you bring your
vehicle to your authorized
MERCEDES-BENZ dealer fo r mainte
nance service.
