Cooling system
The coolant level should be checked before
each ride. In addition, the cooling system
must be bled at the intervals specified in the
periodic maintenance and lubrication chart.
WARNING
EWS00390
Do not remove the radiator cap when the
engine is hot. Scalding hot fluid and steam
may be blown out under pressure, which
could cause serious injury.
When the engine has cooled, place a thick
rag or towel over the radiator cap, and
slowly rotate the cap counterclockwise to
the detent. This procedure allows any re-
sidual pressure to escape. When the hiss-
ing sound has stopped, press down on the
cap while turning counterclockwise and
remove it.
To check the coolant level
1.
Place the snowmobile on a level surface
and apply the parking brake.
2.
Check the coolant level in the coolant
reservoir when the engine is cold. If the
coolant level is below the “LOW” mark,
add coolant until it reaches the “FULL”
mark. (See the following section “Replen-
ishing the coolant” for more details.)
NOTICE:
Hard water or salt water is
harmful to the engine parts. You may
use boiled or distilled water, if soft wa-
ter is not available. Tap water can be
used temporarily in an emergency.
