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. Open the radiator cap as follows. Wait until the
engine has cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over
the radiator cap and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual
pressure to escape. When the hissing sound has stopped, press down on the cap while turning counterclock-
wise and remove it.
NOTE:
If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the rec-
ommended coolant as soon as possible.

Wait until the engine
has cooled.
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system. Check the coolant level in the
reservoir tank and/or radiator.
Add coolant (See NOTE.)
