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.

differs according to the make of the anti-freeze and the
ambient temperature. Refer to SAE J1034 standard,
more specifically also to SAE J814c.
