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.
9. Start the engine, and then let it idlefor several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
10. 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.
EAU20101
To check the coolant level
1. Place the vehicle on the center-
stand.
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 the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
NOTE:

The coolant should be between the
minimum and maximum level marks. Recommended engine oil:
See page 8-1.
Oil quantity:
Without oil filter element replace-
ment:
3.80 L (4.02 US qt)
(3.34 Imp.qt)
With oil filter element replace-
ment:
3.90 L (4.12 US qt)
(3.43 Imp.qt)

3. If the coolant is at or below the
minimum level mark, remove pan-
el B (See page 6-5.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the pan-
el.
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 of
the coolant will be reduced.
WARNING

EWA10380
Never attempt to remove the radiator
cap when the engine is hot.
NOTE:


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

If the engine overheats, see page
6-39 for further instructions.
EAU20450
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove the seat. (See
page 3-13.)

3. Remove cowling B and panel B.
(See page 6-5.)
4. Remove the fuel tank bolts, and
then lift the fuel tank to position it
away from the coolant reservoir.
(Do not disconnect the fuel hoses!)
5. Place a container under the engine
to collect the used coolant.
6. Remove the radiator cap retaining
bolt and the radiator cap.
WARNING

EWA10380
Never attempt to remove the radiator
cap when the engine is hot.
7. Remove the coolant drain bolts todrain the cooling system.
8. Remove the coolant reservoir bolt.
9. Pull the coolant reservoir upward
and away from the vehicle.
10. Drain the remaining coolant fromthe coolant reservoir by opening
the cap, then turning the reservoir
upside down.
11. Install the coolant reservoir by
placing it in the original position,
then installing the bolt.
12. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
13. Install the coolant drain bolts, and
then tighten them to the specified
torque.
NOTE:

Check the washers for damage and re-
place them if necessary.
14. Pour the recommended coolant
into the radiator until it is full.

the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
15. Install the radiator cap, start the
engine, let it idle for several min-
utes, 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 and the cap retaining bolt.
17. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
18. Install the fuel tank.
WARNING

EWA11290

Before installing the fuel tank,
make sure that the fuel hoses
are not damaged. If any fuel
hose is damaged, do not start
the engine but have a Yamaha
dealer replace the hose, other-
wise fuel may leak.

Make sure that the fuel hoses
are properly connected and
routed, and not pinched.

Be sure to place the fuel tank
breather hose in the original po-
sition.
19. Install the panel, the cowling, and
the seat.
20. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system. Antifreeze/water mixture ratio:
1:1
Recommended antifreeze:
High-quality ethylene glycol
antifreeze containing corro-
sion inhibitors for aluminum
engines

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 hissing
sound 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 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 NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
