instead of coolant, replace it with
coolant as soon as possible, other-
wise the cooling system will not be
protected against frost and corrosion.
If water has been added to the cool-
ant, have a Yamaha dealer check the
antifreeze content of the coolant as
soon as possible, otherwise the effec-
tiveness of the coolant will be re-
duced.
