13. Pour the recommended coolant into the radia-
tor until it is full.
CAUTION:
ECB00400
● If coolant is not available, use distilled water
or soft tap water instead. Do not use hard wa-
ter or salt water since it is harmful to the en-
gine.
● If water has been used instead of coolant, re-
place it with coolant as soon as possible,
otherwise the engine may not be sufficiently
cooled and the cooling system will not be
protected against frost and corrosion.
● If water has been added to the coolant, have
a Yamaha dealer check the antifreeze con-
tent of the coolant as soon as possible, oth-
erwise the effectiveness of the coolant will
be reduced.
14. Install the radiator cap, start the engine, let it
idle for several minutes, and then turn it off.
15. Remove the radiator cap to check the coolant
level in the radiator. If it is low, add sufficient
coolant until it reaches the top of the radiator,
and then install the radiator cap.
16. Start the engine, and then check for coolant
leakage.
NOTE:
If any leakage is found, have a Yamaha dealer
check the cooling system.
17. Install the panels and the front carrier.
