WARNING
Make sure that no foreign
material enters the final trans-
mission case.
Make sure that no oil gets on
the tire or wheel.
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
EAU20070
Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20101
To check the coolant level
1. Place the vehicle on the centers-
tand.
NOTE:
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
1. Maximum level mark
2. Minimum level mark
2. Check the coolant level in the
coolant reservoir.
NOTE:
The coolant should be between the
minimum and maximum level marks.
Recommended final transmission
oil:
See page 8-1.
Oil quantity:
0.15 L (0.16 US qt) (0.88 Imp.qt)
Tightening torque:
Final transmission oil drain bolt:
22 Nm (2.2 m•kgf, 15.9 ft•lbf)

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.

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.
