NOTE:The engine oil should be between theminimum and maximum level marks.
5. If the engine oil is at or below the
minimum level mark, remove the
oil filler cap, and then add sufficient
oil of the recommended type to
raise it to the correct level.

en the oil filler cap.
To change the engine oil (with or

off.
2. Place an oil pan under the engine
to collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from

the O-ring of the new oil filter car-
tridge.NOTE:Make sure that the O-ring is properlyseated.
8. Install the new oil filter cartridge
with an oil filter wrench, and then

with a torque wrench.9. Install the coolant reservoir cover
by installing the bolts.
10. Install the cowling.
11. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
NOTE:Check the washer for damage and re-place it if necessary.12. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.
CAUTION:
ECA11620


In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.


Make sure that no foreign mate-rial enters the crankcase.

for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
NOTE:After the engine is started, the engine
oil level warning light should go off if theoil level is sufficient.CAUTION:
ECA10400
If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha dealercheck the vehicle.
14. Turn the engine off, and then
check the oil level and correct it if
necessary.
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.
EAU20112
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:

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.
NOTE:The coolant should be between theminimum and maximum level marks.3. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir cover by remov-
ing the bolts, remove the reservoir
cap, and then add coolant to the
maximum level mark.

CAUTION:
ECA10470


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 engine may not be
sufficiently cooled and the cool-
ing system will not be protected
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 possible,
otherwise the effectiveness ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
4. Install the reservoir cap, and then
install the coolant reservoir cover
by installing the bolts.NOTE:

The radiator fans are automatically
switched on or off according to the
coolant temperature in the radia-
tor.


If the engine overheats, see page6-43 for further instructions.
EAU20343
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.2. Remove panel A, and cowlings A
and B. (See page 6-6.)
3. Place a container under the engine
to collect the used coolant.
4. Loosen the clamp screw, and then
disconnect the air intake duct.
5. Remove the radiator cap.

6 Engine overheating
WARNING
EWA10400


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.
NOTE:If coolant is not available, tap water can be temporarily used 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 NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
