NOTE:The coolant should be between theminimum and maximum level marks.3. If the coolant is at or below the minimum level mark, remove cowl-
ing A. (See page 6-5.)
4. Loosen the coolant reservoir cap retainer bolt, and then lift the re-
tainer upward.
5. Remove the coolant reservoir cap, and then add coolant to the maxi-
mum level mark.
CAUTION:
ECA10470
use only YAMAHA GENUINE
COLANT. Using coolan other than
recommended, could cause damage
to oil seal and o-rings, as whell
as to the cooling system. If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
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 effectiveness ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
6. Install the coolant reservoir cap.
7. Place the coolant reservoir cap re- tainer in the original position, and
then tighten the bolt to the speci-
fied torque.
8. Install the cowling.
