How Can I flush my Cooling System

I understand that on some of these newer cars you have to pull plugs out to flush the cooling system to bleed out the air. Is there any special way to flush out a Fiat 500 ? We used to go down and get a flush kit at the local auto parts store and do them ourselves.

The drain plug is on the bottom of the radiator on the back side on the driver's side. Basically to flush, fill it, run it, drain it, refill it, do that several times. If you use a chemical flush, follow the instructions on the bottle.

As best I can tell the coolant reservoir is above the rest of the cooling system, so air will naturally bubble out.

Is it possible to clean the coolant reservoir somehow? I know it makes no difference in the scope of things, but ever since putting in WaterWetter the bottle has been nasty, fogged, and yellowed. Any suggestions? I'm fine with removing it and sloshing something around in it if I have to.
