PERIODIC SERVICE

2. Before employing LLC-mixed cooling water, flush the

radiator with fresh water. Repeat this procedure 2 or 3
times to clean up the radiator and engine block from
inside.

3. Mixing the LLC

Premix 50% LLC with 50% clean soft water. When
mixing, stir it up well, and then fill into the radiator.

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 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.

The above data represent industry standards that
necessitate minimum glycol content in the
concentrated anti-freeze.

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 severe or dusty
conditions. 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/cm , 30 psi).

[Engine model : D1703-EBG, V2203-EBG]

5. Replace the element every year or every 6 cleanings.

Make sure the wing bolt for the element is tight
enough. If it is loose, dust and dirt may be sucked into
the engine, causing premature wearing down the
cylinder liner and piston ring earlier, and thereby
resulting in poor power output and need for engine
repair.

[Engine model : V3300-EBG]

If the air cleaner is equipped with the secondary element,
start it in the following manner :
Take steps (1) through (4) foregoing.
5. Replace the primary element every year or every 6

cleanings. If the primary element is heavily stained,
replace it sooner. At this time, also replace the
secondary element.

6. The secondary element should be removed only if it is

to be replaced.

7. To protect the engine, do not remove the secondary

element in normal servicing of the primary element.
