2. Check to see if there is any obstacle around the
cooling air inlet or outlet;
3. Check to see if there is any dirt or dust between
radiator fins and tube;
4. Check to see if the fan belt is too loose; and
5. Check to see if radiator water pipe is clogged.
B
Cleaning Radiator Core (outside)
If dust is between the fin and tube, wash it away with
running water.
A
Do not clean radiator with firm tools such as spatulas
or screwdrivers. They may damage the delicate fins or
tubes. It can cause coolant leaks or decrease cooling
performance.
A
Be careful to keep water off of electrical parts.
B
Cleaning the Radiator
Clean the cooling system of the engine every 500 hours.
In addition, clean it before adding anti-freeze and before
stopping use of anti-freeze.
B
Anti-Freeze
To avoid personal injury:
A
When using anti-freeze, put on some protection
such as rubber gloves (Anti-freeze contains
poison.).
A
If should drink anti-freeze, throw up at once and
take medical attention.
A
When anti-freeze comes in contact with the skin or
clothing, wash it off immediately.
A
Do not mix different types of antifreeze. The
mixture can produce chemical reaction causing
harmful substances.
A
Anti-freeze is extremely flammable and explosive
under certain conditions. Keep fire and children
away from anti-freeze.
A
When draining fluids from the engine, place some
container underneath the engine body.
A
Do not pour waste onto the grounds, down a drain,
or into any water source.
A
Also, observe the relevant environmental
protection regulations when disposing of
antifreeze.
Always use a 50/50 mix of long-life coolant and clean soft
water in KUBOTA engines.
Contact KUBOTA concerning coolant for extreme
conditions.
1. Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
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 (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 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 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.
