CAUTION:
ECA10471


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 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.
5. Install the panel.NOTE:

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


If the engine overheats, see page6-42 for further instructions.
EAU39002
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove cowlings D and E. (See
page 6-6.)3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap.
WARNING

Never attempt to remove the radiatorcap when the engine is hot.
5. Remove the coolant drain bolt to
drain the cooling system.
6. Move the hose clamp in the direc-
tion shown, and then disconnect
the radiator hose to drain the radi-
ator.

removing the bolts.
8. Remove the coolant reservoir cap,
and then turn the coolant reservoir
upside down to empty it.9. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant reservoir by in-
stalling the bolts.
11. Connect the radiator hose, and
then move the hose clamp back to
its original position.
12. Install the coolant drain bolt, and
then tighten it to the specified
torque.
NOTE:Check the washer for damage and re-place it if necessary.13. Pour the recommended coolant
into the reservoir to the maximum
level mark, and then install the
coolant reservoir cap.
14. Pour the recommended coolant
into the radiator until it is full.

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.17. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
18. Install the cowlings.

Air filter element The air filter element must be replaced
at the intervals specified in the periodic
maintenance and lubrication chart.
Have a Yamaha dealer replace the air
filter element.

6Engine 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 capwhile 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.
There is
leakage.
There is
no leakage.
