10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
TIPAfter the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient.NOTICE
ECA10401
If the oil level warning light flickers
or remains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer check
the vehicle.11. Turn the engine off, wait a few min-utes until the oil settles, and then
check the oil level and correct it if
necessary.
12. Install the cowlings.
EAU20070
Coolant The 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.
EAU38173
To check the coolant level 1. 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 the
side can result in a false reading.
2. Check the coolant level in the cool-ant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below theminimum level mark, remove the
coolant reservoir cover by remov-
ing the bolts, remove the coolant
reservoir cap, and then add cool-
ant to the maximum level mark.
WARNING! Remove only the coolant reservoir cap. Never at-
tempt to remove the radiator
cap when the engine is hot.
[EWA15161]
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.

6of 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.
[ECA10472]
4. Install the reservoir cap, and then
install the coolant reservoir cover
by installing the bolts.
EAU47303
To change the coolant1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove cowlings B and C. (See page 6-8.)
3. Place a container under the engine to collect the used coolant. 4. Remove the radiator cap.
WARNING! Never attempt to re-
move the radiator cap when the
engine is hot.
[EWA10381]

tem.

6. Remove the coolant reservoir cov-
er by removing the bolts, and then
remove the coolant reservoir cap. 7. Remove the coolant reservoir by
removing the bolts, and then turn
the reservoir upside down to emp-
ty it.
8. After the coolant is completely drained, thoroughly flush the cool-
ing system with clean tap water.
9. Install the coolant reservoir by in- stalling the bolts.
10. Install the coolant drain bolt and its new gasket, and then tighten the
bolt to the specified torque. 11. Pour the recommended coolant
into the reservoir to the maximum
level mark, and then install the
coolant reservoir cap.
12. Pour the recommended coolant into the radiator until it is full.
13. Install the radiator cap, start the engine, let it idle for several min-
utes, and then turn it off.
14. 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.

Engine overheating
WARNING
EWAT1040
●
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.
●
Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent to allow any residual pressure to escape. When the hissing sound 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 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.
There is
leakage.
There is
no leakage.
