1. Coolant reservoir cap
2. Maximum level mark
3. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove
panel A (See page 6-6.), remove
the reservoir cap, add coolant to
the maximum level mark, and
then install the reservoir cap and
the panel.
ECA10470
CAUTION:
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 coo-
lant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the coo-
ling system will not be protec-
ted 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 possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.

WARNING
Never attempt to remove the radia-
tor cap when the engine is hot.
NOTE:
The radiator fan is automatically
switched on or off according to
the coolant temperature in the
radiator.
If the engine overheats, see page
6-33 for further instructions.

WARNING
Never attempt to remove the radia-
tor cap when the engine is hot.
The coolant must be changed at the
intervals specified in the periodic
maintenance and lubrication chart.
Have a Yamaha dealer change the
coolant.

2. If the battery will be stored for
more than two months, check the
specific gravity of the electrolyte
at least once a month and fully
charge the battery whenever
necessary.
3. Fully charge the battery before
installation.
4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals and that the breather hose is
properly routed, in good condi-
tion, and not obstructed.
ECA10600
CAUTION:
If the breather hose is positioned in
such a way that the frame is expo-
sed to electrolyte or gas expelled
from the battery, the frame could
suffer structural and external
damages.

Replacing the fuses
The main fuse box and the fuse box,
which contains the fuses for the indi-
vidual circuits, are located under
panel B. (See page 6-6.)
If a fuse is blown, replace it as
follows.
1. Turn the key to “
e” and turn off
the electrical circuit in question.
1. Main fuse
2. Radiator fan fuse
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.
ECA10640
CAUTION:
Do not use a fuse of a higher ampe-
rage rating than recommended to
avoid causing extensive damage to
the electrical system and possibly a
fire.
Specified fuses:
Main fuse:
20 A
Radiator fan fuse:

Engine overheatingEWA10400
s s
WARNING
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the his-
sing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
Wait until the
engine has cooled.Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.
The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.
Add coolant. (See NOTE.)
Start the engine. If the engine overheats again, have a
Yamaha dealer check and repair the cooling system.
There is
leakage.
There is
no leakage.
NOTE:
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
