*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 man-
ufacturer and type in the same coolant percentage.
*Never add any long-life coolant of different manufactur-
er. (Different brands may have different additive compo-
nents, 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.
A The above data represent industry standards that
necessitate a minimum glycol content in the
concentrated anti-freeze.
BRadiator cement
As the radiator is solidly constructed, there is little
possibility of water leakage. Should this happen,
however, radiator cement can easily fix it. If leakage is
serious, contact your local KUBOTA dealer.
AIR CLEANER
Since the air cleaner employed on this engine is a dry
type, never apply oil to it.
1. Open the evacuator valve once a week under
ordinary conditions - or daily when used in a dusty
place. This will get rid of large particles of dust and
dirt.
2. Wipe the inside air cleaner clean with cloth if it is dirty
or wet.
3. Avoid touching the element except when cleaning.
4. When dry dust adheres to the element, blow
compressed air from the inside turning the element.
Pressure of compressed air must be under 205 kPa
(2.1 kgf/ , 30 psi).
5. Replace the element every year or every 6
cleanings.
A Make sure the wing bolt for the element is tight
enough. If it is loose, dust and dirt may be sucked in,
wearing down the cylinder liner and piston ring
earlier and thereby resulting in poor power output.
A Do not overservice the air cleaner element.
Overservicing may cause dirt to enter the engine
causing premature wear. Use the dust indicator as a
guide on when to service.
