tank with the mixture.·
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
4. The procedure for the mixing of water and
antifreeze differs according to the make of the
antifreeze and the ambient temperature. Refer
to SEA 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%.

*At 1.013×10 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 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.)
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.
The vehicle's genuine long-life coolant has a

service life of 2 years. Be sure to change the
coolant every 2 years.
NOTE:

The above data represents industry standards
that necessitate a minimum glycol content in
the concentrated antifreeze.

When the coolant level drops due to
evaporation, add water only to keep the
antifreeze mixing ratio less than 50%. In case
of leakage, add antifreeze and water in the
specified mixing ratio before filling into the
radiator.
