• 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, follow the relevant environmental
protection regulations when disposing of the
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 using LLC-mixed cooling water, fill the
radiator with fresh water and empty it again.
Repeat this procedure 2 times 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.
• 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 use 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 as
follows.
Changing the coolant
every 2000 hours or every 2 years
whichever comes faster
• The procedure for the mixing of water and the
antifreeze differs according to the make of the
antifreeze and the ambient temperature. Refer to
SAE J1034 standard, more specifically also to SAE
J814c.
