TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
4. Reservoir cap
3. If the coolant is at or below the
minimum level mark, remove pan-
el E (See page 7-7.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the
panel. WARNING! Remove only
the coolant reservoir cap. Nev-
er attempt to remove the radia-
tor cap when the engine is hot.
NOTICE:If coolant is not avail-
able, use distilled water or soft
tap water instead. Do not use
hard water or salt water since it
is harmful to the engine. If wa-
ter has been used instead of
coolant, replace it with coolant
as soon as possible, otherwise
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 an-
tifreeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.
Coolant reservoir capacity
(up to the maximum level mark):
0.50 L (0.52 US qt) (0.44 Imp.
EAU33031
Changing the coolant
The coolant must be changed at the
intervals specified in the periodic
maintenance and lubrication chart.
Have a Yamaha dealer change the
coolant. WARNING! Never attempt
to remove the radiator cap when
the engine is hot.

Engine overheatingEWA10400
WARNING0
●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.
TIP
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 low.
Check the cooling
system for leakage.
The coolant level
is OK.
There is
leakage.
There is no
leakage.
Have a Yamaha dealer check
and repair the cooling system.
Start the engine. If the engine overheats again, have
a Yamaha dealer check and repair the cooling system.
Add coolant. (See TIP.)
