63. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir breather hose
from the guide, and then remove
the coolant reservoir cap.4. Add coolant to the maximum level
mark, and then install the coolant
reservoir cap. WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.
[EWA15161]
NOTICE: If
coolant is not available, use dis-
tilled water or soft tap water in-
stead. Do not use hard water or
salt water since it is harmful to
the engine. If water has been
used instead of coolant, replace
it with coolant as soon as possi-
ble, otherwise the cooling sys-
tem will not be protectedagainst frost and corrosion. If
water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.

69. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant drain bolt, and
then tighten it to the specified
torque.
TIPCheck the washer for damage and re-place it if necessary.
11. Install the coolant reservoir and its
reservoir cover by placing them in
the original position, and then in-
stalling the bolts.
12. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.13. Install the radiator cap.
14. Install the coolant reservoir cap.
15. Start the engine, let it idle for sev-
eral minutes, and then turn it off.
16. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap, radiator cap retainer and radi-
ator cap retaining bolt.17. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.

er hose through the guide as
shown.Tightening torque:
