Coolant
Check level!
The coolant level is too low.

Add coolant (
page 249).

If you have to add coolant frequently, have the cooling
system checked by an authorized Mercedes-Benz Center
immediately.
Warning!
G
Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts. You can be seriously burned.
!Do not ignore the low engine coolant
level warning. Extended driving with
the message and symbol displayed
may cause serious engine damage not
covered by the Mercedes-Benz Limited
Warranty.
Do not drive without sufficient amount
of coolant in the cooling system. The
engine will overheat causing major
engine damage.

Coolant
Stop, engine off!
The poly-V-belt could be bro-
ken.

Stop immediately and check the poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise the engine will over-
heat due to an inoperative water pump which may result
in damage to the engine. Notify an authorized
Mercedes-Benz Center.
If it is intact:

Do not continue to drive with this message displayed.
Doing so could result in serious engine damage that is
not covered by the Mercedes-Benz Limited Warranty.

Observe the coolant temperature gauge in the instru-
ment cluster (
page 29).

Drive immediately to the nearest authorized
Mercedes-Benz Center.
Coolant
Visit
workshop!
The cooling fan for the coolant
is malfunctioning.

Observe the coolant temperature gauge in the instru-
ment cluster (
page 29).

Have the fan replaced immediately.

380 Technical dataFuels, coolants, lubricants, etc.Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which pro-
vides:

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 approximately -22°F (-30°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
The coolant solution must be used year
round to provide the necessary corrosion
protection and increase in the boil-over
protection. Refer to Service Booklet for re-
placement interval.Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Service Booklet is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see Facto-
ry Approved Service Products pamphlet)
are used to renew the coolant concentra-
tion or bring it back up to the proper level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approximately
- 22°F [-30°C]). If you use a solution that is
more than 55% anticorrosion/antifreeze
(freeze protection to approximately
- 49°F [-45°C]), the engine temperature
will increase due to the lower heat transfer
capability of the solution. Therefore, do not
use more than this amount of anticorro-
sion/antifreeze.If the coolant level is low, water and
MB 325.0 anticorrosion/antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Center.

381 Technical data
Fuels, coolants, lubricants, etc.
Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum parts. (Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life.)
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0 anticorrosion/anti-
freeze 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 an authorized Mercedes-Benz
Center for service.
