How do you bleed air from coolant system on 2004 2.2 ecotech alero?

To bleed air from the coolant system on a 2004 2.2 Ecotec Alero, first ensure the engine is cool. Remove the radiator cap and fill the radiator with coolant until it's full. Start the engine and let it run with the heater set to maximum; this helps circulate coolant and expel trapped air. Keep an eye on the coolant level and top it off as necessary until no more bubbles appear and the coolant level stabilizes. Afterward, replace the radiator cap securely.
