Replacing Cooling Water
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. Procedure:
• Remove the header tank cap.
• Remove the bottom radiator hose
of the radiator and drain the cooling
water.
• After draining the cooling water,
reconnect the hose.
• Fill radiator and engine with cooling
water via the header tank.
CAUTION
!
Beware of scalding hot
water.
Wait until the temperature goes down before
draining the Cooling water. Otherwise, hot
water may splash to cause scalding.
