Coolant
Check the coolant level in the reservoir tank when
the engine is cold. (The coolant level will vary with
engine temperature.) The coolant level is satisfac-
tory if it is between the “FULL” and “LOW” marks
on the tank. If the coolant level is at or below the
“LOW” level, add tap water (soft water) to bring the
level up to “FULL”. Change the coolant every two
years. (See pages 8-31 ~ 8-39 for details.)CAUTION:
Hard water or salt water is harmful to the en-
gine. You may use distilled water if you can’t
get soft water. Reservoir tank capacity:
0.29 L
From “LOW” to “FULL” level:
0.17 L

2. If the level is low, remove the coolant reser-
voir cap, and then add coolant or distilled wa-
ter to raise it to the specified level.CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use soft water if you can’t get
distilled water. _NOTE:_

If water is added, have a Yamaha dealer
check the antifreeze content of the coolant as
soon as possible.
