Important safety notes
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
- corrosion protection
- antifreeze protection
- raising the boiling point
The engine cooling system is filled at the factory with coolant that contains an antifreeze/corrosion inhibitor that ensures protection down to approximately -35 °F (-37 °C).
Only add coolant that has been premixed
with the desired antifreeze protection.
Otherwise, the engine could be damaged.
Further information on coolants and on
filling can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com. You can
also consult an authorized Mercedes-Benz
Center.
Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
If the coolant has antifreeze protection down to -35 °F (-37 °C), the boiling point of the coolant under operating conditions is approximately 266 °F (130 °C).
Your vehicle has a range of aluminum components. Aluminum components in the engine make it necessary to use antifreeze/corrosion inhibitor coolant that has been specifically formulated to protect the aluminum parts. Using other antifreeze/corrosion inhibitors without these characteristics affects the service life.
The coolant must be used throughout the year in order to maintain the necessary corrosion protection and to provide protection from overheating. In the Service Booklet, you can find information on the intervals for renewal.
The renewal interval is determined by the coolant type and the engine cooling system design. The renewal interval in the Service Booklet is only valid if the coolant is renewed or filled up with Mercedes-Benz approved products. Therefore, only use MB 325.0 or 326.0 anticorrosion/antifreeze or another Mercedes-Benz approved product of the same specification.
Information on other products with the same specifications that are approved by Mercedes-Benz can be obtained at an authorized Mercedes-Benz Center or on the Internet at http://bevo.mercedes-benz.com.
The coolant is checked at every maintenance interval at an authorized Mercedes-Benz Center.
The antifreeze/corrosion inhibitor
concentration in the engine cooling system
should:
- be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 °F (-37 °C ).
- not exceed 55% (antifreeze protection to
-49 °F [-45 °C ]); otherwise, heat will not
dissipate as effectively.
If the coolant level is too low, MB 325.0 or 326.0 anticorrosion/antifreeze should be added. Have the engine cooling system checked for possible leaks.
