utes for the oil to settle, and then
check the oil level one last time.
NOTICE: Do not operate the ve-
hicle until you know that the en-
gine oil level is sufficient.

Why YamalubeYAMALUBE oil is a Genuine YAMAHA
Part born of the engineers’ passion and
belief that engine oil is an important liq-
uid engine component. We form teams
of specialists in the fields of mechanical
engineering, chemistry, electronics and
track testing, and have them develop
the engine together with the oil it will
use. Yamalube oils take full advantage
of the base oil’s qualities and blend in
the ideal balance of additives to make
sure the final oil clears our performance
standards. Thus, Yamalube mineral,
semisynthetic and synthetic oils have
their own distinct characters and value.
Yamaha’s experience gained over
many years of research and develop-
ment into oil since the 1960’s helps
make Yamalube the best choice for
your Yamaha engine.

CoolantThe coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.TIPIf genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilledwater at a 1:1 ratio.
EAU20097
To check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold.
1. Park the vehicle on a level surface.
2. With the vehicle in an upright posi- tion, look at the coolant level in theRecommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark):0.25 L (0.26 US qt, 0.22 Imp.qt)
Radiator (including all routes): 1.93 L (2.04 US qt, 1.70 Imp.qt)

reservoir.
3. If the coolant is at or below the minimum level mark, remove the
coolant reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to re-
move the radiator cap when the
engine is hot.
[EWA15162]
4. Add coolant to the maximum level mark. 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 coolant reservoir cap.
EAU33032
Changing the coolant
The coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart. Have a
Yamaha dealer change the coolant.
WARNING! Never attempt to remove
the radiator cap when the engine is
hot.

WARNING
EWA10401

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 hissingsound 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 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.
