At the time of manufacture, the cooling system is filled with a 50 :50 mixture of distilled water and ethylene glycol 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 (-24 °F) . If the motorcycle is to be exposed to temperatures below -31 °C (-24 °F), this mixing ratio should be increased up to 55 % or 60 % according to the figure. CAUTION • Use a high quality ethylene glycol base anti-freeze, mixed with distilled water . Do not mix an alcohol base anti-freeze and different brands of anti-freeze. • Do not rut in more than 60%anti-freeze or less than 50 %. (Refer to the right figure.) • * Do not use a radiator anti-leak additive.

After the engine cools, wrap a thick cloth around cap and carefully remove the cap by turning 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 farmful; • * If the comes in contact with skin or eyes, flush with water. • * If swallowed accidentally, induce vomiting and call physician immediately . • * Keep it away from children .

(=6-6) • * Remove the radiator cap ® . • * Connect the tester 02 to the filler. A WARNING Do not remove the radiator cap when the engine is hot. • * Give a pressure of about 110 kPa (1.1 kgf/cm 2, 15 .6 psi) and see if the system holds this pressure for 10 seconds. • * If the pressure should fall during this 10-second interval, it means that there is a leaking point in the system. In such a case, inspect the entire system and replace the leaking component or part. A WARNING When removing the radiator cap tester, put a rag on the filler to prevent spouting of engine coolant. CAUTION Do not allow the pressure to exceed the radiator cap release pressure, or the radiator can be damaged
