Widetrak Cooling System
Surge Tank
Keep the level of the coolant inside the surge tank
between high and low marks. Coolant level will rise and fall
depending on the coolant temperature.
Always add coolant when the cooling system is COLD.
Fill Tube / Pressure Cap
The fill tube is the primary cooling system fill location.
Always add and remove coolant from the fill tube.
The pressure cap maintains a system pressure of 19 - 20
psi. (131 - 144 kPa). The cap features a locking vent used
to purge air from the cooling system without spilling
coolant. When operating the snowmobile, the vent must
be closed and locked to prevent engine overheating.
