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 2000
hours or every 2 years whichever comes faster.
A The above data represent industry standards that
necessitate a minimum glycol content in the
concentrated antifreeze.

BChecking Radiator Hoses and Clamps
To avoid personal injury or death:
A Be sure to stop the engine and remove the key
before checking radiator hose and clamp.
A Allow engine and coolant to cool down
sufficiently before checking.
Inspect every year; replace if any deterioration (crack,
hardening, scar, or deformation) or damage occurred.
1. If hose clamps are loose or water leaks, tighten bands
securely.
2. Replace hoses and tighten hose clamps securely, if
radiator hoses are swollen, hardened or cracked.
Replace hoses and hose clamps every 4 years or earlier
if checked and found that hoses are swollen, hardened or
cracked.
BChecking Intake Air Line
1. Check to see that hoses and hose clamps are tight and
not damaged.
2. If hoses and clamps are found worn or damaged,
replace or repair them at once.
(1) Radiator hoses (2 hoses)
(2) Clamp bands (4 clamps)
