DEUTZ cooling system protectant must be pur-
chased in drums under Order No. 01011490 (5
litres) or 1221 1500 (210 litres). These are nitrite,
amine and phosphate-free, and provide effective
protection against corrosion, cavitation and freez-
ing.
If the above mentioned cooling system protectant
is unavailable, the following products may be
used in exceptional cases.
Manufacturer Product designation
AVIA AVIA Antifreeze Extra
ARAL Antifreeze Extra
BASF Glysantin G 48
DEA DEA Radiator Antifreeze

The cooling system protectant in the coolant should
not fall below or exceed the following concentration
:
Filling volume, see chart over page in combina-
tion with specifications in Chapter 9.1.
The use of other cooling system protectants, e.g.
chemical anti-corrosion agents, is possible in
exceptional cases. Consult DEUTZ Service.
In the case of liquid-cooled engines, special
attention must be paid to the treatment and
control of the coolant, as the engine may
otherwise become damaged as a result of
corrosion, cavitation and freezing.
The treatment of the coolant is carried out by
adding a cooling system protectant to the
cooling water.
The cooling system must be continuously moni-
tored, see 5.1. In addition to checking the
coolant level, this also involves checking the
concentration of the cooling system protectant.
The cooling system protectant concentration
can be checked with commercially available
testers (example: gefo glycomat ®).

If nitrite-based cooling system
protectants are mixed with
amine-based agents, danger-
