Coolant
The coolant is a mixture of water and a cor-
rosion inhibitor /antifreeze agent or water
and a coolant additive without antifreeze
properties. In order to maintain corrosion
protection and to increase the boiling
point, the coolant must remain in the cool-
ing system all the year round.
Coolant mixing ratios
!
The antifreeze/corrosion inhibitor con-
centration in the coolant should be
checked every six months.
Renew the coolant every three years,
since the level of corrosion protection
gradually decreases.
Water alone is not permissible as a
coolant, even if antifreeze protection is
not required. The water in the coolant
must satisfy the requirements speci-
fied on sheet no. 310 of the Mercedes-
Benz Specifications for Service Prod-
ucts.
If the water quality is not sufficient you
must filter and/ or treat the water.
Information is available from any
Mercedes-Benz Service Centre.
Do not increase the concentration of
corrosion inhibitor/ antifreeze beyond
55% by volume (= maximum antifreeze
protection). Above this concentration,
antifreeze protection deteriorates and
heat dissipation is less effective.
During the colder months, check corro-
sion protection and antifreeze more
frequently.

Environmental note
H
Unless they are handled properly, coolant
can constitute a risk both for people and for
the environment. Coolant must not be al-
lowed to get into the sewage system, sur-
face waters, the ground water or the ground
itself. Dispose of used coolant in an environ-
mentally friendly manner. Observe the legal
requirements. Further information on how
to handle, store and dispose of coolants is
available from any Mercedes-Benz Service
Centre.
