EBU23470
Coolant
The coolant level should be checked before each
ride. In addition, the coolant must be changed at
the intervals specified in the periodic maintenance
and lubrication chart.
EBU23501
To check the coolant level
1. Place the ATV on a level surface.
NOTE:

The coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture.
2. Check the coolant level in the coolant reser-
voir.
NOTE:

The coolant should be between the minimum and
maximum level marks.3. If the coolant is at or below the minimum level
mark, remove the seat. (See page 4-11.)
4. Open the coolant reservoir cover.

5. Remove the reservoir cap, add coolant or dis-
tilled water to the maximum level mark, and
then install the reservoir cap.
CAUTION:

ECB00401

If coolant is not available, use distilled water
or soft tap water instead. Do not use hard wa-ter or salt water since it is harmful to the en-
gine.

If water has been used instead of coolant, re-
place it with coolant as soon as possible,
otherwise 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, oth-
erwise the effectiveness of the coolant will
be reduced.
6. Close the coolant reservoir cover.
7. Install the seat.
NOTE:

If the engine overheats, see page 8-52 for further
instructions.
