Liquid Cooling System; Radiator - Arctic Cat Wildcar Trail Service Manual

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 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.
