Kubota BX261D User Manual

• 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 from a
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 an anti-corrosive
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.
