Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
TIP
If genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU54164To check the coolant level
1. Wait for the engine to cool. The coolant level will vary with engine
temperature.
2. Place the vehicle on the center- stand.
3. Remove the left cowling vent pan- el. (See page 3-40.)
4. Look at the coolant reservoir. 5. If the coolant is at or below the mi-
nimum level mark, remove the
coolant reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to re-
move the ra diator cap when the
en gine is hot.
[EWA15162]
6. Add coolant or distilled water to
raise the coolant to the maximum
level mark, and install the coolant
reservoir cap. NOTICE: If coolant
is not availab le, use distille d wa-
ter or soft tap water instea d. Do
not use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has b een
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e red uced.
[ECA10473]
7. Install the panel.

Do not remove the ra diator cap when the en gine an d ra diator are hot.
Scal din g hot flui d an d steam may b e blown out un der pressure, which
coul d cause serious injury. Be sure to wait until the eng ine has cooled.
 Place a thick ra g, like a towel, over the ra diator cap, an d then slowly ro-
tate the cap counterclockwise to the detent to allow any resi dual pres-
