How do you bleed the air from the coolant system on a Polaris scrambler 850?

To bleed the air from the coolant system on a Polaris Scrambler 850, start by ensuring the vehicle is on a level surface and the engine is cool. Remove the radiator cap and fill the system with coolant to the appropriate level, then start the engine and let it run until it reaches operating temperature, allowing the thermostat to open. Rev the engine slightly to help circulate the coolant, and observe for bubbles escaping from the radiator filler neck. Once the bubbles stop and the coolant level stabilizes, replace the radiator cap securely.
