NOTE:
Check the washer for damage and re-
place it if necessary.
17. Pour the recommended coolant
into the reservoir to the maximum
level mark, and then install the
coolant reservoir cap.
18. Install the coolant reservoir cover
by installing the bolts.
19. Insert the fuel hoses into the guide
and place them in their original po-
sition.
20. Install cowling B.
21. Pour the recommended coolant
into the radiator until it is full.
CAUTION:
ECA10470
●
If 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 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 of
the coolant will be reduced.
22. Install the radiator cap, start the
engine, let it idle for several min-
utes, and then turn it off.
23. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap.
24. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
25. Connect the air intake duct, and
then tighten the clamp screw.
26. Install the panel and the cowling.
