67. Remove the cylinder drain plug
covers on the outside of the cylin-
der blocks by removing the
screws.8. Remove the rubber coolant drain
plugs to drain the coolant from the
engine.
9. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the water pump drain bolt,
and then tighten it to the specified
torque.
NOTE:@ Check the washer for damage and re-
place it if necessary. @
11. Install the rubber coolant drain
plugs, and then install the cylinder
drain plug covers.NOTE:@ Check the rubber plugs for damage
and replace them if necessary. @12. Turn the coolant drain cock to
“OFF”.
13. Pour the recommended coolant
into the reservoir to the maximum
level, and then install the cap.
14. Pour the recommended coolant
into the radiator until it is full.

CAUTION:@ l
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
l
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
l
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.
@15. Install the radiator cap, start the
engine, let it idle for several min-
utes, 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.
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.
18. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
19. Install the cowling and the panel. Antifreeze/water mixture ratio:
1:1
Recommended antifreeze:
High-quality ethylene glycol
antifreeze containing corrosion
inhibitors for aluminum engines
Coolant quantity:
Total amount:
3.05 L
Coolant reservoir capacity:
0.3 L

6 Engine overheating
EW000070
WARNING
@ l
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. Be sure to wait until the engine has cooled.
l
After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
@NOTE:@ If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
