4. Leave the cap off of the radiator to allow any possible air
to escape. Start the engine and let it idle for 5-10 minutes
or until the thermostat opens and allows coolant to flow
through the system.
5. Slightly loosen the bleed screw (C) on the thermostat cover
to let air escape. If no air is present, a steady stream of
coolant will stream out. If air is present, the screw will
bubble and sputter as the air escapes.
6. Squeeze the coolant lines by hand to help purge the system
of air.
7. Add Polaris Premium Antifreeze to the radiator if the level
goes down.
8. Tighten the bleed screw to 70 ± 10 in.lbs. (8 ± 1.13 Nm) on
the thermostat housing and properly install the radiator cap.
9. 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 surge tank
only after you have completely filled the cooling system at
the radiator filler neck.
10. Repeat this procedure, if overheating still occurs.
If overheating occurs after repeating this procedure,
proceed to Procedure 2.
PROCEDURE 2:
1. Drive the machine onto a slight incline or use properly
weight rated ramps. Place the machine in Neutral and set
the parking brake. Block the rear wheels. The radiator
neck should be above the level of the top of the engine.
2. Remove radiator cap and top off coolant. Fill the surge tank
to the full line.
3. Leave the cap off of the radiator to allow any possible air
to escape. Start the engine and let it idle for 5-10 minutes
or until the thermostat opens and allows coolant to flow
through the system.
NOTE: If there is air in the system you will see air
bubbles forming through the radiator fill neck.
4. Add coolant as needed. If no bubbles are seen at the filler
neck, the system should be purged of air.
5. Install the radiator cap and turn off the machine.
WARNING
Be sure to install the radiator cap before
shutting off the engine.
Coolant may spit out of the radiator.

CAUTION
Be sure the engine has cooled and there is no
pressure built up in the cooling system before
removing the radiator cap. The coolant maybe
hot and could cause severe injury or burns.
WARNING
Be sure to install the radiator cap before
shutting off the engine.
Coolant may spit out of the radiator.
