CAUTION:_

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
_ Never attempt to remove the radia-
tor cap when the engine is hot. _4. Close the reservoir cap, and then
install the coolant reservoir cover
by installing the bolts.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
6-45 for further instructions.

To change the coolant
1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
2. Remove panel A, and cowlings A
and B. (See pages 6-6–6-8 for
panel and cowling removal and in-
stallation procedures.)
3. Place a container under the en-
gine to collect the used coolant.
4. Remove the radiator cap.

617. 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.
18. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
19. Install the panel and the cowlings.

Checking the air filter element The air filter element should be
checked at the intervals specified in the
periodic maintenance and lubrication
chart. Check the air filter element more
frequently if you are riding in unusually
wet or dusty areas.
1. Remove the rider seat. (See
page 3-13 for rider seat removal
and installation procedures.)
2. Remove the fuel tank bolts and
slightly lift the fuel tank.3. Turn the fuel cock lever to “OFF”,
and then disconnect the hoses
and the fuel sender coupler.
NOTE:_ Before removing the hoses, mark them
to ensure that they will be reinstalled in
their correct positions. _

WARNING
@

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 hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
@aNOTE:@ 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.
There is
leakage.
