Do not use strong acid or alkaline water. Use of the
genuine Long-Life Coolant (LLC) mixed by 33 to 50 % is
recommended.

°F), fill the cooling system with Long-Life Coolant (LLC)
and soft water mix. As a general rule, the ratio of LLC
should be 50% as shown in the table below. If the ratio is
above 50%, the engine may overheat.
