MAINTENANCE MANUAL
3.2.3. Coolant
The coolant specification must meet requirements of:
CES 14603
To fill the cooling circuit, use the coolant
in the mixing ratio of 50%/50% with high-
-quality water (thermal protection up to
-37 °C).
The maximum admissible concentration
of the coolant is 60% (thermal protection
up to -54 °C).
Change the coolant every 2,000 hours of
operation, after 2 years at the latest.
Note:
The machines are filled with a cooling solution with the Bant-
leon Avia Antifreeze NG coolant, specification CES 14603, ASTM
D 4985, ASTM D 6210 at the manufacturer’s during the produc-
tion.
It is a coolant based on monoethyleneglycol containing silicates.
It does not contain phosphates, nitrates, amines and borates.
There is an Avia NG label placed at the point to fill the coolant
into the machine.
Refill the cooling circuit with the same or
a completely miscible coolant of the re-
quired specification.
If the use of a different, immiscible cool-
ant is necessary, the cooling circuit must
be completely drained and cleaned with
clean water repeatedly, at least 3 times.
However, it is not allowed to use a coolant
of a different specification than stated by
the engine manufacturer.
The coolant protects the cooling system
from freezing, corrosion, cavitation, over-
heating, etc.
It is forbidden to operate the machine
without coolant even for a short time.
It is forbidden to use a coolant of a dif-
ferent than prescribed specification and
base. The engine and the cooling system
can get damaged and the warranty lost.
Always check the ratio of antifreeze cool-
ing agent in the coolant with a refractom-
eter before the winter season starts.
Water quality
Do not use hard water with a higher content of calcium and
magnesium, which brings calculus formation, and with a higher
content of chlorides and sulphates, which causes corrosion; re-
fer to CUMMINS Engine Operation and Maintenance Manual.
The maximum content of compounds of calcium and magne-
sium is 170 milligrams – hardness of water.
The maximum content of compounds of chlorine is 40 milli-
grams.
The maximum content of compounds of sulphur is 100 milli-
grams.
Safety instructions:
1) Protect your hands with protective gloves.
2) In case of ingestion immediately seek medical
treatment.
3) In case of contact with skin or clothing immedi-
ately wash the affected area with clean water.
4) Do not mix different types of coolants. The mix-
ture can cause a chemical reaction with formation
of harmful substances.
