before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.

To check 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. Remove the radiator cap and check the coolant level in the radi-
ator. WARNING! Never attempt
to remove the radiator cap when
the engine is hot.

TIPThe coolant should be at the bottom of
the radiator filler neck. The level will
change with variation of engine temper-ature. 3. If the coolant is below the correct
coolant level, add coolant, and
then install the radiator cap.
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 water
has been used instead of cool-
ant, replace it with coolant as
soon as possible, otherwise the
cooling system will not be pro-
tected against frost and corro-
sion. If water has been added to
the coolant, have a Yamaha
dealer check the antifreeze con-
tent of the coolant as soon as
possible, otherwise the effec-
tiveness of the coolant will be
reduced.
