Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the ins-
pection and maintenance procedures and schedules described in the Owner’s Manual.
EWA11151
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment dama-
ge. Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures pro-
vided in this manual, have the vehicle inspected by a Yamaha dealer.
Before using this vehicle, check the following points:

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.
EAU39086
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
●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.
2. Check the coolant level in the
coolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
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 6-8).
4. Remove the coolant reservoir
cap, add coolant to the maxi-
mum level mark, and then install
the reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to
remove the radiator cap when
the engine is hot.
[EWA15161]. NOTI-
CE: 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 coo-
lant, replace it with coolant as
soon as possible, otherwise
the cooling system will not be
protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.

EAUS1601
To change the coolant
1. Put the vehicle on a level surface
and let the engine cool if neces-
sary.
2. Remove cowling C and panel A.
(See page 6-8).
3. Place a container under the engi-
ne to collect the used coolant.
4. Remove the radiator cap retai-
ning bolt, radiator cap retainer
and radiator cap. WARNING!
Never attempt to remove the
radiator cap when the engine is
hot.

8. After draining the coolant, tho-
roughly flush the cooling system
with clean tap water.
9. Replace the coolant drain bolt
washer if it is damaged, and then
tighten the coolant drain bolt to
the specified torque.
10. Connect the coolant reservoir
hose.
Tightening torque:

11. Pour the recommended coolant
into the radiator until it is full.
12. Install the radiator cap.
13. Run the engine several minutes.
Stop the engine and recheck the
coolant level in the radiator. If it is
low, add more coolant until it rea-
ches the top of the radiator.
14. Install the radiator cap, radiator
cap retainer and radiator cap
retaining bolt.
15. Fill the coolant reservoir with
coolant up to the maximum level.
16. Install the coolant reservoir cap
and check for coolant leakage.TIP
If any leakage is found, ask a Yamaha
dealer to inspect the cooling system.
17. Install the cowling and the panel.

The air filter element should be clea-
ned or replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart. Have a Yamaha
dealer clean or replace the air filter
element.Recommended antifreeze:

Engine overheatingEWA10400
●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.
TIP
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.
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 TIP.)
Start the engine. If the engine overheats again, have a
Yamaha dealer check and repair the cooling system.
