Cooling system
1. Check the coolant level in the coolant
reservoir when the engine is cold as the
coolant level will vary with engine temper-
ature. The coolant level should be
between the maximum and minimum
marks.

3. Open the coolant reservoir cover.
4. Remove the coolant reservoir cap, and
then add coolant or distilled water to raise
it to the specified level.
5. Install the coolant reservoir cap.
6. Close the coolant reservoir cover.
7. Install the seat.

To change the coolant
w
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 put a thick rag over
the cap when opening. Allow any remaining
pressure to escape before completely
removing the cap.
1. Put the ATV on a level place.
2. Remove the radiator cover bolts, and then
remove the radiator cover.
3. Place a container under the engine and
remove the coolant drain bolts.
