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
EWS00381
Do not remove the coolant reservoir cap
when the engine is hot. Scalding hot fluid
and steam may be blown out under pres-
sure, which could cause serious injury.
When the engine has cooled, place a thick
rag or towel over the coolant reservoir
cap, and slowly rotate the cap counter-
clockwise to the detent. This procedure
allows any residual pressure to escape.
When the hissing sound has stopped,
press down on the cap while turning coun-
terclockwise and remove it.

To check the coolant level
1.
Place the snowmobile on a level surface
and apply the parking brake.
2.
Remove the shroud and the right side
cover [RST1NTF / RST1NTFY (see page
59 for the procedures)], or open the
shroud [RST9N (see page 61 for the pro-
cedures)].
3.
Check the coolant level in the coolant
reservoir when the engine is cold. If the
coolant level is below the “COLD LEVEL”
mark, add coolant until it reaches the
“COLD LEVEL” mark. (See the following
section “Replenishing the coolant” for
more details.)
NOTICE:
If coolant is not
available, use distilled water or soft
tap water instead. Do not use hard
water or salt water since it is harmful
to the engine. If water has been used
