Anti-freeze
CAUTION
To avoid personal injury:
A
When using anti-freeze, put on
some protection such as rubber
gloves (Anti-freeze contains
poison.).
A
If should drink anti-freeze, throw up
at once and take medical attention.
A
When anti-freeze comes in contact
with the skin or clothing, wash it off
immediately.
A
Do not mix different types of anti-
freeze. The mixture can produce
chemical reaction causing harmful
substances.
A
Anti-freeze is extremely flammable
and explosive under certain
conditions. Keep fire and children
away from anti-freeze.
A
When draining fluids from the
engine, place some container
underneath the engine body.
A
Do not pour waste onto the
grounds, down a drain, or into any
water source.
A
Also, observe the relevant
environmental protection regulations
when disposing anti-freeze.
If it freezes, coolant can damage the cylinders and
radiator. If the ambient temperature falls below 0°C
(32°F) or before a long-term storage, let out cooling
water completely, or mix fresh water with long-life
coolant and fill the radiator and recovery tank with the
mixture.
1. Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the
radiator with fresh water and empty it again. Repeat
this procedure 2 or 3 times to clean up the inside.
3. Mixing the LLC
Put the LLC in cooling water in the percentage (%)
for a target temperature. When mixing, stir it up well,
and then fill into the radiator.
4. The procedure for the mixing of water and anti-
freeze differs according to the make of the anti-
freeze and the ambient temperature. Refer to SAE
J1034 standard, more specifically also to SAE
J814c.
A
When the anti-freeze is mixed with water, the anti-
freeze mixing ratio must be less than 50%.
*At 1.013 x10
5
Pa (760 mmHg) pressure (atmospheric).
A higher boiling point is obtained by using a radiator
pressure cap which permits the development of
pressure within the cooling system.
5. Adding the LLC
(1) Add only water if the mixture reduces in amount
by evaporation.
(2) If there is a mixture leak, add the LLC of the
same manufacturer and type in the same
mixture percentage.
*Never add any long-life coolant of different
manufacturer. (Different brands may have different
additive components, and the engine may fail to
perform as specified.)
6. When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains anti-corrosive
agent. If mixed with the cleaning agent, sludge may
build up, adversely affecting the engine parts.
7. Kubota's genuine long-life coolant has a service life
of 2 years. Be sure to change the coolant every 2
years.
A
The above data represent industry standards that
necessitate a minimum glycol content in the
concentrated anti-freeze.
A
When the coolant level drops due to evaporation,
add water only to keep the anti-freeze mixing ratio
less than 50%. In case of leakage, add anti-freeze
and water in the specified mixing ratio before filling
into the radiator.
