etc. of these coolant specifications also apply. It is imperative that the correct concentration (50/50) is
used in their application and, of course, further dilution is not permitted!
Approval status:
Coolants for all vehicle and engines (Basis 325.0) Sheet 326.0
Coolants for commercial vehicle and industrial engines (Basis 325.2) Sheet 326.2
Coolants for commercial vehicle and industrial engines (Basis 325.3) Sheet 326.3
The regulations for each respective Sheet 325.x are to be transferred correspondingly to Sheet
326.x.
At the time of compiling these regulations it is possible that not all the Sheets 326.x are represented with
approved products.
2.Coolant additives (General information)
Normally, coolant consists of water and anticorrosion/antifreeze agents. The anticorrosion/antifreeze
agents (ethylene glycol with corrosions inhibitors) in the cooling system have to fulfill, among other
things, the following functions:
to provide sufficient corrosion and cavitation protection for all cooling system components
freezing point depression (antifreeze)
increasing boiling point
For corrosion protection purposes the coolant
approx. 50 vol.-% Anticorrosion/antifreeze agents are added if the expected ambient temperatures do not
require an even higher concentration. This concentration (50 vol %) offers frost protection up to approx. -
37°C. A higher concentration is only necessary if the ambient temperatures are even lower.
Even with extremely low ambient temperatures, not more than 55 vol.-% anticorrosion/antifreeze agent
should be used, because at this level the maximum antifreeze protection is reached and a greater
concentration reduces the antifreeze protection again and decreases the heat dissipation (55 vol.-%
corresponds to antifreeze protection down to approx. -45°C).
Should these coolant regulations fail to be observed then corrosion and damage to the cooling
system are inevitable.
The admixture of anticorrosion/antifreeze agent serves to increase the boiling point. By raising the
pressure the boiling temperature can be increased yet further. Both physical relationships are put to use in
modern cooling systems - the maximum coolant temperature is raised, without increasing the danger of
boiling. In keeping with the higher temperature level the cooling performance is also greater. Only
approved products (Sheet 325.0/326.0 or 325.2 or 326.2, 325.3 or 326.3 as well as 312.0 or 311.0)

provide reliable cooling system protection. In special cases (commercial-vehicle engines, no antifreeze
specification) coolant additives can be used that are primarily corrosion protection additives. In this case
item 2.3 is valid.
As an exception, if neither anticorrosion/antifreeze agent conforming to Sheet 325.0 nor coolant additives
without addition of antifreeze conforming to Sheet 312.0 are available, proceed according to point 2.4
(exception: OM 500 and OM 900). The systems described under items 2.2/2.3/2.4 are not compatible
with each other. It is recommended to mix the entire coolant quantity outside the engine.
2.1 Anticorrosion/antifreeze agent for passenger-car engines
Alongside the correct constitution of the cooling water (point 1.2.2), care must be taken to ensure that
only anticorrosion/antifreeze agents as approved for all engines in accordance with Sheet 325.0 are used.
These products serve to guarantee that, in particular, an effective protection against corrosion is provided
for all light-alloy parts in the cooling system and they are also specified for all passenger-car engines.
In order to ensure that the protection against corrosion is effective, the anticorrosion/antifreeze agent must
remain in the cooling system throughout the year - including when in tropical climates - and regardless of
the operating conditions. In countries with high outside temperatures this is also important in terms of
raising the boiling point.
In the event that these regulations are not observed the cooling system may suffer from damage by
corrosion. As a consequence of corrosion deposits there is a danger that ducts in the radiators (engine
overheating) and heat exchangers (poor heat output) get plugged up thus causing damage to the engine.
As a result of the optimizations we have carried out on the system of engine/coolant/cooling system, in
the majority of our newer passenger cars, a replacement of coolant is not necessary until reaching 15
operating years or 250,000 km (whichever comes first). This may not apply to some models; in these
cases the maintenance booklet will stipulate another regulation.
2.2 Anticorrosion/antifreeze agent for commercial-vehicle engines (normal case)
(not: BR 600, BR 100 and BR 200)
The coolant in commercial-vehicle engines is made up of both water and anticorrosion/antifreeze agent
(refer to item 1.1.1) and as such offers ideal protection against corrosion and cavitation.
All the approved products on the Sheets 325.2, 325.3 or 325.0 which are part of the Specifications for
Operating Fluids can be used to select an anticorrosion/antifreeze agent. However, it should be noted that
passenger vehicle engines built into commercial vehicles must be filled like passenger vehicles (e.g. OM
601 in T1), i.e. a product conforming to Sheet 325.0 and 326.0 must be used.
Products that are not listed in Sheets 325.0 and 326.0, or 325.2 and 326.2, or 325.3 and 326.3 are not
approved and are therefore not to be used under any circumstances.
Anticorrosion/antifreeze agents or coolants conforming to Sheet 325.3 or 326.3 may be used for
longer than other products due to their composition. The change interval is set at 5 years (refer to

the regulation filling of 50 vol.% (-37°C). When topping up (after coolant loss), an anticorrosion/
antifreeze agent content in the coolant of at least 50 vol. % (antifreeze protection down to -37°C) must be
ensured, or the concentration regulations according to point 2.3/2.4.1 must be observed. In closing an
example is given in Overview Section 5.
Non observance a observance of these regulations or the use of non-approved products will
result in serious damage.
The corrosion inhibitors diminish during operation and lose their protective capability. Coolant that is too
old, and has lost its important inhibitors and anti-aging additives, becomes strongly corrosive. The
coolant additives as under Sheets 311.0 and 312.0 will also age. This causes a deterioration in the level of
protection capability, and with regard to coolant refining agents this will also cause the emulsion to break
down.
For this reason it is important to replace the coolant, in order to ensure that its corrosion protection
capability is retained. If necessary the cooling system should be thoroughly cleansed before refilling with
the new coolant. A sufficient level of heat dissipation will only be given if the cooler surfaces are clean.
The maximum permissible period of usage for coolant is cited in Overview Section 5.
The use of approved operatin
g fluids, which naturally include the anticorrosion/antifreeze agents, is
a well-known constituent of the warranty conditions.
4.Disposal of coolants
The coolants are biologically-degradable material.
All statutory regulations or waste water regulations in each individual country with regard to the disposal
of used coolant must be observed.
It is recommended to have the possibilities available for disposing of materials explained by the local
responsible water authorities.
Currently in Germany methods are being compiled for the purification of used coolant. The separate
collection of all used operating fluids is highly recommended.
However, as a consequence of the complex tasks asked of a modern coolant, it is on no account advisable
to use an improperly "recycled" coolant, which has only undergone a mechanical pre-purification process
