This just shows you to use proper coolant or a mix of purified water and 
anti-freeze in the future. Never ever use tap water as the minerals in 
it will form a calcified crust and cause havoc in the engine and radiator.
Remove the thermostat, drain and flush the cooling system good and 
proper using tap water first, than adding a can/bottle of radiator 
cleaner to it, run the engine for about an hour, drain and flush the 
engine thoroughly, drain, re-instal the thermostat and fill up with 
organic coolant, In Europe the green stuff. Do not use inorganic coolant 
(red/purple) as this may be harmful to older type seals and gaskets.
