Cooling system
1. Check the coolant level in the reservoir when
the engine is cold as the coolant level will
vary with engine temperature. The coolant
level should be between the maximum and
minimum marks.
2. If the level is low, remove panel D. (See page
8-17 ~ 8-19 for panel removal and installation
procedures.)

8-55 1. Coolant reservoir drain hose
1. Flexible de vidange du vase d’expansion
1. Manguera de drenaje del depósito de refrigerante
3. Remove the reservoir cap, and then add
coolant or distilled water to raise it to the
specified level.
4. Install the panel.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.


The radiator fan operation is completely auto-
matic. It is switched on or off according to the
coolant temperature in the radiator.
_If your ATV overheats, see page 4-3 for details.Coolant reservoir capacity:
0.25 L

ator until it is full.CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use soft water if you can’t get
distilled water. _

more coolant until it reaches the top of the ra-
diator.
14. Fill the coolant reservoir with coolant up to
the maximum level.
15. Install the coolant reservoir cap and check for
coolant leakage.NOTE:_ If any leakage is found, ask a Yamaha dealer to in-

changed to the recommended coolant as soon as possible.
WARNING
Wait for the engine and radiator to cool before removing the radiator cap. You could be burned by
hot fluid and steam blown out under pressure. Always put a thick rag over the cap when opening.
Allow any remaining pressure to escape before completely removing the cap. Wait until the
engine has cooled.
Check the coolant level in the
reservoir tank and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
