Liquid Cooling System
When filling the cooling system, use premixed Arctic Cat
Antifreeze. While the cooling system is being filled, air
pockets may develop; therefore, open the bleed screw on
the thermostat housing to allow air to bleed from the
cooling system. When clear coolant (no bubbles) is pres-
ent, tighten the bleed screw securely; then fill the cooling
system to the bottom of the stand pipe in the radiator
neck. Run the engine for five minutes after the initial fill,
shut the engine off, and then “top-off” the cooling system
to the bottom of the stand pipe in the radiator neck.

check the coolant level. Add coolant as necessary.
