Cooling System Bleeding Procedure

WARNING
Always wear safety glasses and proper shop clothing
when performing the procedures in this manual. Failing
to do so may lead to possible injury or death.
Use caution when performing these procedures.
Coolant may be hot and may cause severe injury or
burns.
If the coolant level is LOW in the radiator, or if there are
leaks in the system, the coolant system will not draw
coolant from the reservoir tank.
It may be necessary to safely raise the front of the
vehicle 12" (30 cm) to bleed the cooling system.
1. Allow engine and cooling system to completely cool.
Be sure the engine has cooled and no pressure is built
up in the cooling system before removing the pressure
cap. The coolant may be hot and could cause severe
injury or burns.
2. Remove Left side panel, required PVT ducting and
Center panel under the front rack.
3. Remove the pressure cap (1) and add the necessary
amount of Polaris Premium Antifreeze to the radiator
filler neck.
