correct, immediately turn the engine
off and have a Yamaha dealer check
the vehicle.
13. Turn the engine off, wait a few min- utes until the oil settles, and then
check the oil level and correct it if
necessary.
EAU20071
CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20095
To check the coolant level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIP
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.

Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level in the cool- ant reservoir.
TIPThe coolant should be between theminimum and maximum level marks. 3. If the coolant is at or below the
minimum level mark, remove the
reservoir cap. WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.

mark, and then install the reservoir
cap. NOTICE: 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 cool-
ant as soon as possible, other-
wise 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.

EAU76810
To change the coolant1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove panel B. (See page 7-9.)
3. Place a container under the engine to collect the used coolant.
4. Remove the radiator cap retaining bolt, radiator cap retainer and radi-
ator cap. WARNING! Never at-
tempt to remove the radiator
cap when the engine is
hot.
[EWA10382]
5. Remove the coolant reservoir cov- er and coolant reservoir by remov-
ing the bolts and collars.

6. Remove the coolant reservoir cap.
7. Drain the coolant from the coolant
reservoir by turning it upside down. 8. Install the coolant reservoir and its
cover by placing them in the origi-
nal position, and then installing the
collars and bolts.
9. Remove the coolant drain bolt and its gasket to drain the coolant from
the cooling system.
10. After the coolant is completely drained, thoroughly flush the cool-
ing system with clean tap water.
11. Install the coolant drain bolt and its new gasket, and then tighten the
bolt to the specified torque. 12. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.
13. Install the coolant reservoir cap.
14. Install the radiator cap.
15. Start the engine, let it idle for sev- eral minutes, and then turn it off.
16. Remove the radiator cap to check the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap, radiator cap retainer and radi-
ator cap retaining bolt.
17. Check the coolant level in the res- ervoir. If necessary, remove the
coolant reservoir cap, add coolant

WARNING
EWA10401

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 hissingsound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIPIf coolant is not available, tap water can be temporarily us
ed instead, provided that it is changed to the recommended coolantas 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.

leakage.
There is
no leakage.
