4. The procedure for the mixing of water and anti-freeze
differs according to the make of the anti-freeze. Refer
to SAE J1034 standard, more specifically also to SAE
J814c.
*At 1.013 x 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 cooling system.
5. Adding the LLC
(1) Add only water if the coolant level reduces in the
cooling system by evaporation.
(2) If there is a coolant leak, add the LLC of the same
manufacturer and type in the same coolant
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.)
6. When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains 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. Be sure to change the coolant every 2 years.
