Hard water or salt water is harmful to the
engine. You may use soft water if you can’t
get distilled water.
NOTE:
8If water is added, have a Yamaha dealer
check the antifreeze content of the coolant as
soon as possible.
8The radiator fan operation is completely auto-
matic. It is switched on or off according to the
coolant temperature in the radiator.
If your ATV overheats, see page 8-138 for
details.
