minimum level mark, remove cowl-
ing B. (See page 7-8.)
4. Remove the coolant reservoir cap, add coolant to the maximum level
mark, and then install the reservoir
cap. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the radiator
cap when the engine is
hot.
[EWA15162]
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 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 anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
[ECA10473]
5. Install the cowling.
EAU66520
To change the coolant
1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove cowling B and panel D. (See page 7-8.)
3. Place a container under the engine to collect the used coolant.
4. Remove the radiator cap.
WARNING! Never attempt to re-
move the radiator cap when the
engine is hot.

5. Remove the coolant drain bolt andits gasket to drain the cooling sys-
tem.

6. 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 specified amount of the recommended coolant into the ra-
diator and reservoir. 12. Install the coolant reservoir cap.
13. Loosen the air bleed bolt to allow
any trapped air to escape from the
water pump.

15. Pour the specified coolant into the radiator until it is full.
16. Install the radiator cap.
17. Start the engine, let it idle for sev-
eral minutes, and then turn it off.
18. 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.
19. Start the engine, and then check the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
20. Install the cowling and panel.

Engine overheating
WARNING
EWAT1041

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.
TIPIf 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 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.
