MAINTENANCE
Cooling System
Bleeding the Cooling System
CAUTION! Steam and hot liquids will cause burns to your skin. Never bleed the
cooling system or remove the pressure cap when the engine is warm or hot.
1. Read the entire coolant bleed procedure before beginning.
2. Move the snowmobile into a well-ventilated area. Allow the engine
to cool completely.
3. Open the hood.
4. Remove the coolant pressure
cap carefully.
5. Slowly pour coolant into the
filler neck until the coolant level
reaches the top of the rear cool-
ing loop return line on the inside
of the filler neck. The opaque
coolant reservoir bottle should
be full, but may have a small air
bubble in the top.
CAUTION! Never start the engine
when the pressure cap is removed.
6. Reinstall the pressure cap. Start
the engine and allow it to idle.
7. With the engine idling, observe the coolant level in the reservoir
bottle. Make sure that the coolant level is always visible in the bot-
tle. If the level reaches the bottom of the bottle, stop the engine and
perform step 11 before continuing to step 8.
