Default Radiator flush

Guys, Im going to drain and refill my radiator with new dexcool and water wetter. The coolant looks pretty dirty. How does one bleed the air after?

If you go to www.installuniversity.com and check the thermostat replacement, there's a good write-up. The trick is to disconnect the coolant hose going to the throttle body when refilling slowly, and then run the engine up to normal temp for a few minutes with radiator cap off. Let the engine go through several warm-up cool-down cycles and top off the radiator as needed.
