 Anti-freeze
CAUTION
To avoid personal injury:
• When using anti-freeze, put on some protection such as
rubber gloves (Anti-freeze contains poison.).
• If should drink anti-freeze, throw up at once and take
medical attention.
• When anti-freeze comes in contact with the skin or
clothing, wash it off immediately.
• Do not mix different types of anti-freeze. The mixture can
produce chemical reaction causing harmful substances.
• Anti-freeze is extremely flammable and explosive under
certain conditions. Keep fire and children away from
anti-freeze.
• 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.
• Observe the relevant environmental protection regulations
when disposing of anti-freeze.
If it freezes, coolant can damage the cylinders and radiator. If
the ambient temperature falls below 0 °C or before a long-term
storage, let out coolant completely, or mix fresh water with long-life
coolant (hereafter LLC) and fill the radiator and reserve tank with
the mixture.
1. Long-life coolant comes in several types. Use ethylene glycol
(EG) type for this engine.
2. Before employing LLC-mixed coolant, 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 coolant 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 anti-freeze differs
according to the make of the anti-freeze and the ambient
temperature. Refer to SAE J1034 standard, more specifically
also to SAE J814c.
IMPORTANT
• When the anti-freeze is mixed with water, the anti-freeze
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.
