Cooling water contaminated with rust or water scale
reduces the cooling effect. Even when antifreeze
agent (LLC) is mixed, the cooling water gets
contaminated due to deteriorated ingredients.
Replace the cooling water at least once a year.
1) Remove the radiator cap.
2) Loosen the drain plug at the lower portion of
the radiator and drain the cooling water.
3) After draining the cooling water, tighten the
drain plug.
4) Fill radiator and engine with cooling water.

Beware of scalding by hot water
Wait until the temperature goes down before draining the cooling water.
Otherwise, hot water may splash to cause scalding.
