68. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
NOTE:Check the washer for damage and re-place it if necessary.
9. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.
CAUTION:
ECA11620


In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.


Make sure that no foreign mate-rial enters the crankcase.
10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
NOTE:After the engine is started, the engine
oil level warning light should go off if theoil level is sufficient.CAUTION:
ECA10400
If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha dealercheck the vehicle.
11. Turn the engine off, and then
check the oil level and correct it if
necessary.
12. Install the cowling.

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 ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
5. Install the cowling.NOTE:

The radiator fans are automatically
switched on or off according to the
coolant temperature in the radia-
tor.


If the engine overheats, see page6-44 for further instructions.
EAU42980
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove cowlings B and C. (See
page 6-6.)3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap.
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
5. Remove the coolant drain bolt to
drain the cooling system.6. Remove the coolant reservoir cap.
7. Remove the coolant reservoir by
removing the bolts, and then turn

drained, thoroughly flush the cool-
ing system with clean tap water.
9. Install the coolant reservoir by in-
stalling the bolts.
10. Install the coolant drain bolt, and
then tighten it to the specified
torque.
NOTE:Check the washer for damage and re-place it if necessary.
11. Pour the recommended coolant
into the reservoir to the maximum
level mark, and then install the
coolant reservoir cap.
12. Pour the recommended coolant
into the radiator until it is full.
CAUTION:
ECA10471


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.


If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise 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 content ofthe coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
13. Install the radiator cap, start the
engine, let it idle for several min-
utes, and then turn it off.
14. 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.
15. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
16. Install the cowlings.
