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
Put the LLC in cooling water in the percentage (%)
for a target temperature. When mixing, stir it up
well, and then fill into the radiator.
4. The procedure for the mixing of water and
antifreeze differs according to the make of the
antifreeze and the ambient temperature. Refer to
SAE J1034 standard, more specifically also to
SAE J814c.
IMPORTANT:
¡
When the antifreeze is mixed with water, the
antifreeze mixing ratio must be less than 50%.

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 mixture reduces in
amount by evaporation.
(2) If there is a mixture leak, add the LLC of the
same manufacturer and type in the same
mixture 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.)
