When draining fluids from the engine, place
some container underneath the engine
body.

Do not pour waste onto the grounds, down
a drain, or into any water source.

Also, observe the relevant environmental
protection regulations when disposing of
antifreeze.
If it freezes, coolant can damage the cylinders
and radiator. If the ambient temperature falls
°
℃
below 0 (32 F) or before a long-term storage,
let out cooling water completely, or mix fresh
water with long-life coolant and fill the radiator
and recovery 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
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

standard, more specifically also to SAE
J814c.
IMPORTANT:

When the antifreeze is mixed with water, the
antifreeze mixing ratio must be less than
50%.

(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.
7. The vehicle's genuine long-life coolant has
a service life of 2 years. Be sure to
change the coolant every 2 years.


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
