protection such as rubber gloves. (Antifreeze
contains poison.)

If you should drink antifreeze, throw up at
once and seek medical attention.

When antifreeze comes in contact with the
skin or clothing, wash it off immediately.

Do not mix different types of Antifreeze.
The mixture can produce chemical reaction
causing harmful substances.

Antifreeze is extremely
explosive under certain conditions. Keep fire
and children away from antifreeze.

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 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.

Adding the LLC
Add only water if the mixture reduces in
amount by evaporation.
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.)
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.
The above data represent industry standards
that require a minimum glycol content in the
concentrated antifreeze.
When the coolant level drops due to
evaporation, add water only to keep the
