6 3. If the coolant is at or below the
minimum 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.
If water has been used insteadof 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.

To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove cowlings B and C. (See
page 6-7.)
3. Place a container under the engine
to collect the used coolant.

WARNING! Never attempt to re-
move the radiator cap when the
engine is hot.

5. Remove the coolant drain bolt and
its gasket to drain the cooling sys-
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.1. Radiator cap

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.
15. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.16. Install the coolant reservoir cover
by installing the bolts.
17. Install the cowlings.

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.
