coolant is not available, use distilled
water or soft tap water instead. Do not
use hard water or salt water since it is
harmful to the engine. If water has
been used instead of coolant, replace
it with coolant as soon as possible,
otherwise the cooling system will not
be protected against frost and corro-
sion. If water has been added to the
coolant, have a Yamaha dealer check
the antifreeze content of the coolant
as soon as possible, otherwise the ef-
fectiveness of the coolant will be re-
duced.
