Cooling system
1. Check the coolant level in the reservoir when
the engine is cold as the coolant level will
vary with engine temperature. The coolant
level should be between the maximum and
minimum marks.
2. If the level is low, remove panel D. (See page
8-17 ~ 8-19 for panel removal and installation
procedures.)

Changing the coolant
WARNING
_ 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. Place the ATV on a level surface.
2. Remove panels E and F. (See pages 8-27 ~
8-29 for removal and installation procedures.)
3. Place a container under the engine, and then
remove the coolant drain bolt. (Use a trough
or a similar object as shown to prevent cool-
ant from spilling on the footrest.)
4. Remove the front carrier and panel C. (See
pages 8-23 and 8-25 for removal and installa-
tion procedures.)
