TIPThe engine oil should be between the minimum
and maximum level marks.5. If the engine oil is at or below the minimum
level mark, add sufficient oil of the recom-
mended type through the engine oil tank filler
hole to raise it to the correct level. NOTICE:Be sure the engine oil is at the correct lev-
el, otherwise engine damage may result.
[ECB00851]
TIPWhen adding oil, be careful not to overfill the en-
gine oil tank; the oil level rises faster starting from
the half-level-portion on the dipstick.6. Insert the dipstick into the engine oil tank filler
hole, and then tighten the engine oil tank filler
cap. NOTICE: Make sure that the engine oil
tank filler cap is securely tightened; other-
wise, oil may seep out when the engine is
running.
[ECB00362]
To change the engine oil (with or without oil fil-
ter element replacement)
1. Place the ATV on a level surface.
2. Start the engine, warm it up for several min-
utes, and then turn it off.
3. Place an oil pan under the engine to collect
the used oil.
4. Remove the crankcase engine oil filler cap
and the crankcase engine oil drain bolt.

6. Check the washers for damage, and replace if
necessary.
TIPSkip steps 7–10 if the oil filter element is not being
replaced.7. Remove the oil filter element cover by remov-
ing the bolts, and then remove the oil filter el-
ement.

the engine oil tank drain bolt, and then tighten
them to the specified torques.
12. Install the crankcase engine oil filler cap, and
then tighten it to the specified torque.
13. Pour only 1.3 L (1.37 US qt, 1.14 Imp.qt) of
the specified amount of the recommended en-
gine oil through the engine oil tank filler hole,
and then install and tighten the oil tank filler
cap.
14. Start the engine, rev it several times, and then
turn it off.15. Remove the engine oil tank filler cap, and then
gradually fill the oil tank with the remaining oil
quantity while regularly checking the oil level
on the dipstick.
16. Install and tighten the engine oil tank filler cap.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down.NOTICEECB00300In order to prevent clutch slippage (since the
engine oil also lubricates the clutch), do not
mix any chemical additives. Do not use oils
with a diesel specification of “CD” or oils of Tightening torques:

8 3. If the coolant is at or below the minimum level
mark, remove the coolant reservoir cap, add
coolant or distilled water to the maximum level
mark, and then install the reservoir cap.
NOTICE: If coolant is not available, use
distilled water or soft tap water instead. Do
not use hard water or salt water since they
are harmful to the engine. If water has
been used instead of coolant, replace it
with coolant as soon as possible, other-
wise the cooling system will not be pro-
tected 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,
otherwise the effectiveness of the coolant
will be reduced.
[ECB01011]
TIPThe radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.
If the engine overheats, see page 8-50 for fur-
ther instructions.EBU23542To change the coolant
WARNING
EWB01890Wait for the engine and radiator to cool before
removing the radiator cap. You could be
burned by hot fluid and steam blown out under
pressure. Always place a thick rag over the cap
when opening. Allow any remaining pressure
to escape before completely removing the cap.1. Place the ATV on a level surface.
2. Remove panel A. (See page 8-9.)
3. Place a container under the engine, and then
remove the coolant drain bolt.
Coolant reservoir capacity (up to the maximum
level mark):
0.25 L (0.26 US qt, 0.22 Imp.qt)

6. Disconnect the hose on the coolant reservoir
side, and then drain the coolant from the cool-
ant reservoir.
7. After draining the coolant, thoroughly flush the
cooling system with clean tap water.
8. Replace the coolant drain bolt washer if it is
damaged, and then tighten the coolant drain
bolt to the specified torque.
