WARNING
Risk of scalding and burns when the expansion tank cap (radiator cap) is opened due to high pressure in the cooling
system.
WARNING
Before removing the radiator cap, stop the engine and let it cool down sufficiently. When removing it, turn it slowly
to release the pressure.
Coolant contaminated with rust or water scale reduces the cooling effect. Even when antifreeze agent (LLC) is mixed, the
coolant gets contaminated due to deteriorated ingredients. Replace the coolant at least once a year.
Remove the radiator cap.
Loosen the drain plug at the lower portion of the radiator and drain the coolant.
After draining the coolant, tighten the drain plug.
Fill radiator and engine with coolant.
