Always use a 50/50 mix of long-life coolant and clean soft
water in KUBOTA engines.
Consult your local KUBOTA dealer 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, fill the
radiator with fresh water and empty it again.
Repeat this procedure 2 or 3 times to clean up the
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 and the
ambient temperature. Refer to SAE J1034 standard,
more specifically also to SAE J814c.
A When mixing the anti-freeze with water, the anti-freeze
mixing ratio is 50%.
* 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 mixture leak, add the LLC of the same
manufacturer and type in the mixing ratio 50%.
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.
