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
upper coolant pipe or the water pump housing to allow air to
bleed from the cooling system. When clear coolant (no bub-
bles) is present, 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.
CAUTION
After operating the vehicle for the initial 5-10 minutes,
stop the engine, allow the engine to cool down, and
check the coolant level. Add coolant as necessary.
