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.
IMPORTANT :
• When mixing the antifreeze with water, the
antifreeze mixing ratio is 50%.

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
a. Add only water if the coolant level reduces in
the cooling system by evaporation.
b. If there is a mixture leak, add the LLC of the
same manufacturer and type in the mixing ratio
50%.
IMPORTANT :
• 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.
NOTE :
• The above data represent industry
standards that necessitate a minimum glycol
content in the concentrated antifreeze.

somewhere in the electrical system.
If any of the fuses should blow, replace with a new one
of the same capacity.
IMPORTANT :
• Before replacing a blown fuse, determine why
the fuse blew and make any necessary repairs.
Failure to follow this procedure may result in
serious damage to the vehicle electrical system.
Consult your local KUBOTA Dealer for specific
information dealing with electrical problems.
Replacement procedure
1. Disconnect the negative cable of the battery.
2. Open the seats and remove the utility box and
maintenance cover.
