To check the coolant level
Check the coolant level in the coolant reser-
voir when the engine is cold. If the coolant lev-
el is below the LOW mark, add coolant until
it reaches the FULL mark. (See the following
section Replenishing the coolant for more
details.)
CAUTION:

Hard water or salt water is harmful to the
engine parts. You may use boiled or dis-
tilled water, if soft water is not available.
Tap water can be used temporarily in an
emergency.
Bleeding the cooling system
The cooling system must be bled of air if the
coolant reservoir becomes empty, if air can be
seen in the cooling system, or if there is a
cooling system leak. Consult a Yamaha deal-
er.
CAUTION:

Operating the engine with an improperly
bled cooling system can cause overheat-
ing and severe engine damage.

moval procedures.)

add coolant until it reaches the FULL
mark.
