IMPORTANT
• When the anti-freeze is mixed with water, the anti-freeze
mixing ratio must be less than 50 %.
* At 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.
• Add only water if the mixture reduces in amount by
evaporation.
• If there is a mixture leak, add the LLC of the same
manufacture and type in the same mixture percentage.
* Never add any long-life coolant of different manufacturer.
(Different bands 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 anticorrosive 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.
NOTE
• The above data represent industry standards that
necessitate a minimum glycol content in the concentrated
anti-freeze.
• 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 in to the radiator.
