4. 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.

*1 At 1.013 × 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 cool-
ing system.
5. Adding the LLC
a. Add only water if the mixture level is reduced by
evaporation.
b. If there is a mixture leak, add LLC of the same
manufacturer and type in the same mixture
percentage.
IMPORTANT :
• 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.
6. When the LLC is mixed, do not employ 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.
7. Kubota's genuine long-life coolant has a service life
of 2 years. Change the coolant every 2000 hours or
every 2 years, whichever comes first.
NOTE :
• The above data represents industry standards
that necessitate a minimum glycol content in
the concentrated antifreeze.
