Bleeding t h e Cooling System
3. Tip the snowmobile slightly onto its right side. Cycle the RPM
from idle to enough RPM (4000) to get coolant to flow, but not
enough to engage the clutch. This allows air to bleed from the rear
crossover tube.
NOTE: There must be enough coolant flow to purge the air from the
crossover hose or rear cooler so you can observe this air
reaching the bottle.
4. Tilt the machine slightly onto its left side so that the coolant bottle
is the highest point in the cooling system. Cycle the RPM as
outlined in step 3.
NOTE: There must be enough coolant flow to purge the air from the
front close-off cooler so you can observe the air reaching the
bottle.
5. Return the snowmobile to its upright position and loose n the bleed
scre w at the top of the water outlet manif old. Whe n all trappe d air
has bee n pur ged, tighten the screw.
6. Turn off the engine and release the parking brake. Allow the
system to cool completely.
NOTE: After cool-down, three (3) or more ounces of coolant may
have to b e added.
7. Remove the pressure cap and check the coolant level. Add coolant
to the fill line if necessary.
