MAINTENANCE MANUAL
3.2.3. Coolant
Yanmar engines:
Coolant
The coolant specification must meet requirements of:
ASTM D6210
ASTM D4985
JIS K-2234
SAE J814C, J1941, J1034 or J2036
To fill the cooling circuit, use the coolant in the mixing
ratio of 50 % / 50 % with high-quality water (thermal pro-
tection up to -37 °C).
Change the coolant every 2,000 hours, after 2 years at
the latest.
Note:
The machines are filled with a cooling solution with the Bantleon
Avia Antifreeze NG coolant, specification SAE J 1034 at the ma-
nufacturer‘s during the production.
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 required specification.
If the use of a different, immiscible coolant is necessa-
ry, 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, overheating, etc.
It is forbidden to operate the machine without coolant
even for a short time.
It is forbidden to use a coolant of a different than prescri-
bed specification and base. The engine and the cooling
system can get damaged and the warranty lost.
Always check the ratio of antifreeze cooling agent in the
coolant with a refractometer 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.
The maximum content of compounds of calcium and magnesi-
um is 170 milligrams – hardness of water.
The maximum content of compounds of chlorine is 40
milligrams.
The maximum content of compounds of sulphur is 100
milligrams.
Safety instructions:
1) Protect your hands with protective gloves.
2) In case of ingestion immediately seek medical treatment.
3) I n case of contact with skin or clothing immediately
wash the affected area with clean water.
4) Do not mix different types of coolants. The mixture can
cause a chemical reaction with formation of harmful
substances.
