8. Slightly loosen the bleed screw (C) on the cylinder
head to let air escape. If no air is present, a steady

screw will bubble and sputter as the air escapes.
9. Tighten the bleed screw to specification and properly
install the pressure cap.
Coolant Bleed Screw:

NOTE: If there is air in the system you will see
air bubbles forming through the radiator filler
neck.
10. Add Polaris Premium Antifreeze to the radiator filler
neck if the level goes down. If no bubbles are seen at
the filler neck, the system should be purged of air.
WARNING
Be sure to install the pressure cap before shutting off
the engine.
Coolant may spit out of the radiator.
11. Stop the engine and let cool, top off the radiator filler
neck with coolant. If you hear or see a "glug" at the
filler neck, or there is a dropping of the coolant level,
indicating that coolant has been pulled into the
system; Fill the recovery bottle only after you have
completely filled the cooling system at the radiator
filler neck.
