D At 1.013 x 10 Pa (760mmHg) 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 mixture reduces in amount
by evaporation.
(2) If there is a mixture leak, add the LLC of the same
manufacturer and type in the same mixture
percentage.
D 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 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.
A The above data represent industry standards that
necessitate a minimum glycol content in the
concentrated antifreeze.
A When the coolant level drops due to evaporation, add
water only to keep the antifreeze mixing ratio less than
50%. In case of leakage, add antifreeze and water in
the specified mixing ratio before filling in to the
radiator.
