11. Properly dispose of used coolant.
Coolant capacity (with recovery
tank)
3.9 L (1.0 U.S.gals.)
(1) Radiator cap
(2) Recovery tank
(3) Radiator hose (A) Full
(B) Low
IMPORTANT :
• Do not start engine without coolant.
• Use clean, fresh soft water and antifreeze to
fill the radiator and recovery tank.
• When mixing the antifreeze with water, the
antifreeze mixing ratio is 50%.
• Securely tighten radiator cap and install the
radiator hose. If the cap is loose or
improperly fitted, water may leak out and the
engine could overheat.
2. Antifreeze
WARNING
To avoid personal injury or death:
• When using antifreeze, put on some protection
such as rubber gloves (antifreeze contains
poison).
• If it is swallowed, seek immediate medical help.
Do not make a person throw up unless told to
do so by poison control or a health care
professional. Use standard first aid and CPR for
signs of shock or cardiac arrest. Call your local
Poison Control Center or your local emergency
number for further assistance.
• When antifreeze comes in contact with the skin
or clothing, wash it off immediately.
• Do not mix different types of antifreeze.
The mixture can produce chemical reaction
causing harmful substances.
• Antifreeze is extremely flammable and
explosive under certain conditions. Keep fire
and children away from antifreeze.
• When draining fluids from the engine, place
some container underneath the engine body.
• Do not pour waste onto the ground, down a
drain, or into any water source.
• Also, observe the relevant environmental
protection regulations when disposing of
antifreeze.
Always use a 50/50 mix of long-life coolant and clean
soft water in KUBOTA engines.
Consult your local KUBOTA Dealer concerning coolant
for extreme conditions.
NOTE :
• The following data represent industry standards
that necessitate a minimum glycol content in
the concentrated antifreeze.
• Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this
engine.
• 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.
• Mixing the LLC
Premix 50% LLC with 50% clean soft water. When
mixing, stir it up well, and then fill into the radiator.
• The procedure for the mixing of water and
antifreeze differs according to the make of the
antifreeze and the ambient temperature. Refer to
SAE J1034 standard, more specifically also to SAE
J814c.

A higher boiling point is obtained by using a radiator
pressure cap which permits the development of
pressure within the cooling system.
• Adding the LLC
– Add only water if the mixture reduces in amount
by evaporation.
– 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.)
• When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains anticorrosive
agent. If mixed with the cleaning agent, sludge may
build up, adversely affecting the engine parts.
• KUBOTA's genuine long-life coolant has a service
life of 2 years. Be sure to change the coolant every
EVERY 2000 HOURS OR 2 YEARS PERIODIC SERVICE
