5. Remove the coolant reservoir cap, add cool-
ant 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 aYamaha dealer check the antifreeze con-
tent of the coolant as soon as possible,
otherwise the effectiveness of the coolant
will be reduced.
[ECB01011]

6. Close the coolant reservoir cover.
7. Install the seat.
TIP

If the engine overheats, see page 8-54 for further
instructions.

To change the coolantWARNING
EWB01890
Wait 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.

7. After draining the coolant, thoroughly flush the
cooling system with clean tap water.
8. Replace the coolant drain bolt washers if they
are damaged, and then tighten the coolant
drain bolts to the specified torque.
9. Connect the coolant reservoir hose.
10. Pour the recommended coolant into the reser-voir to the maximum level mark, and then in-
stall the reservoir cap.
NOTICE:
Mix
antifreeze with distilled water only. Howev-
er, if distilled water is not available, soft
water may be used for refilling. Do not use
hard water or salt water since they are
harmful to the engine.

11. Pour the recommended coolant into the radia-
tor until it is full.
12. Install the radiator cap, start the engine, let it
idle for several minutes, and then turn it off.
13. Remove the radiator cap to check the coolant
level in the radiator. If it is low, add sufficient

Cleaning the air filter element
The air filter element should be cleaned at the in-
tervals specified in the periodic maintenance and
lubrication chart. Clean or, if necessary, replace
the air filter element more frequently if you are
riding in unusually wet or dusty areas.
TIP

There is a check hose at the bottom of the air filter
case. If dust or water collects in this hose, empty
the hose and clean the air filter element and air fil-
ter case.1. Place the ATV on a level surface.
2. Remove the seat. (See page 4-11.)
