B Anti-freeze
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 of anti-
freeze.
Always use a 50/50 mix of long-life coolant and clean soft
water in KUBOTA engines.
Contact KUBOTA concerning coolant for extreme
conditions.
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, flush the
radiator with fresh water. Repeat this procedure 2 or 3
times to clean up the radiator and engine block from
inside.
3. Mixing the LLC
Premix 50% LLC with 50% clean soft water. 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. Refer
to SAE J1034 standard, more specifically also to SAE
J814c.
*At 1.013 x 10 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 coolant level reduces in the
cooling system by evaporation.
(2) If there is a coolant leak, add the LLC of the same
manufacturer and type in the same coolant
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 minimum glycol content in the
concentrated anti-freeze.
B Radiator cement
As the radiator is solidly constructed, there is little
possibility of water leakage. Should this happen,
however, radiator cement can easily fix it. If leakage is
serious, contact your local KUBOTA dealer.
