Coolant1. Remove panel C. (See page 7-8
for removal and installation proce-
dures.)
2. Check the coolant level in the res-
ervoir tank when the engine is cold
as the coolant level will vary with
engine temperature. The coolant
level should be between the maxi-
mum and minimum marks.3. If the level is low, remove the rider
seat, open the reservoir tank cap,
and add coolant or distilled water
to the specified level. (See page
3-15 for rider seat removal and in-
stallation procedures.)
4. Install the reservoir tank cap and
rider seat.
5. Install the panel.

CAUTION:@ Hard water or salt water is harmful
to the engine. You may use distilled
water if you can’t get soft water. @NOTE:@ l
If water is added, have a Yamaha
dealer check the antifreeze con-
tent of the coolant as soon as pos-
sible.
l
Have a Yamaha dealer change
the coolant every two years.

Fuse replacementIf a fuse is blown, turn off the main
switch and the switch of the circuit in
question. Install a new fuse of proper
amperage. Turn on the switches and
see if the electrical device operates. If
the fuse immediately blows again, con-
sult a Yamaha dealer.

CAUTION:@ Do not use fuses of higher amper-
age rating than those recommend-
ed. Substitution of a fuse of
improper rating can cause extensive
electrical system damage and pos-
sibly a fire. @

Engine overheating
EW000070
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. Open the radiator cap as follows. Wait until the engine has
cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over the radiator cap
and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual pressure to escape.
When the hissing sound has stopped, press down on the cap while turning counterclockwise and remove it. @NOTE:@ If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the recom-
mended coolant as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir tank and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See NOTE.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system.
