2003 MERCEDES-BENZ CL600 coolant level

342 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 cor-
rosion protection.
If the antifreeze mixture is effective to
–22°F (–30°C), the boiling point of the
coolant 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. You should have it replaced
every 15 years or 150 000 miles
(250 000 km), whichever comes first. Coolant system design and coolant used
stipulate the replacement interval. The
above replacement interval is only applica-
ble if MB 325.0 anticorrosion / antifreeze
solution 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%
anticorrosion / antifreeze [equivalent to
freeze protection to approx. –22°F
(–30°C)]. If you use a solution that is more
than 55% anticorrosion / antifreeze [freeze
protection to approx. –49°F (–45°C)], the
engine temperature will increase due to
the lower heat transfer capability of the so-
lution. Therefore, do not use more than
this amount of anticorrosion / 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 that
the mixture is in accordance with label in-
structions.
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 your authorized Mercedes-Benz
Center.
