7-2 COOLING AND LUBRICATION SYSTEMENGINE COOLANTAt the time of manufacture, the cooling system is filled with a 50:50 mixture of distilled water and ethyleneglycol anti-freeze. This 50:50 mixture will provide the optimum corrosion protection and excellent heat protection,and will protect the cooling system from freezing at temperatures above –31 °C.If the motorcycle is to be exposed to temperatures below –31 °C, this mixing ratio should be increased up to55% or 60% according to the figure.Anti-freezedensity Freezing point50% –30 °C55% –40 °C60% –55 °C* Use a high quality ethylene glycol base anti-freeze, mixed with distilled water. Do not mix analcohol base anti-freeze and different brands of anti-freeze.* Do not put in 60% and more anti-freeze or 50% and less. (Refer to below figure.)* Do not use a radiator anti-leak additive.50% Engine coolant including reserve tank capacityAnti-freezeWater1 400 ml1 400 ml(˚C)0Freezing point–10–20–30–40–50–60Boiling point(˚C)150140130120110(kgf/cm²)1.50.90.50Gauge pressure–7010020 40 60 80 100Density (%)Fig. 1 Engine coolant density-freezingpoint curveFig. 20 10 20 30 40 50 60Density (%)Engine coolant density-boilingpoint curve* You can be injured by scalding fluid or steam if you open the radiator cap when the engine ishot. After the engine cools, wrap a thick cloth around cap and carefully remove the cap byturning it a quarter turn to allow pressure to escape and then turn the cap all the way off.* The engine must be cool before servicing the cooling system.* Coolant is harmful;• If it comes in contact with skin or eyes, flush with water.• If swallowed accidentally, induce vomiting and call physician immediately.• Keep it away from children.
