CoolantThe 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.
EAU20096
Checking the coolant level 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIP
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 theside can result in a false reading.
2. Check the coolant level in the cool- ant reservoir.
TIPThe coolant should be between theminimum and maximum level marks. 3. If the coolant is at or below the
minimum level mark, remove the
reservoir cap. WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.
[EWA15162]
4. Add coolant to the maximum level mark, and then install the reservoir
cap. 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

Air filter elementThe 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.

Checking the engine idling
speedCheck the engine idling speed and, if
necessary, have it corrected by a
Yamaha dealer.
Recommended coolant:
YAMALUBE or other high-quality eth-
ylene glycol antifreeze containing
corrosion inhibitors for aluminum en-
gines
Coolant quantity:
Coolant reservoir (up to the maxi-
mum level mark): 0.25 L (0.26 US qt, 0.22 Imp.qt)
Radiator (including all routes): 2.25 L (2.38 US qt, 1.98 Imp.qt)
Engine idling speed:1200–1400 r/min

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 us
ed 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.
