I'm assuming you have a gm product, 3. 1l. Get the radiator to it's highest point in the air (put car on ramps) remove the radiator cap, run the engine and squeeze the hoses. Also be sure to run the heater.

drain your raidator, refill it, close it up and let your vehicle run for 10 minutes... air pockets should be gone and everythig should be fine

Freon is extremely DANGEROUS. Take your vehicle to an A/C specialist to have the system recharged. It is unwise to attempt this repair yourself.

A very good way to begin draining a coolant system is too jack up your car. Since there are plenty of places within the system which can catch air it is important to make sure the cap or outlet opening is at the highest point possible to allow air to escape.
