How do you bleed air from the cooling system of a Pontiac Grand Am?

It should be a bleeder screw connected to the cooling system, it might be two.If you find it,you should open one at a time.Pour coolant into the system slowly,until coolant start coming out of the bleeder screw and then close it . DO it to the second screw too.Now if you do not have the bleeder screws.Pour coolant into your system slowly and squeeze the top hose until no bubbles come out and the coolant level should go down at this time and then pour alittle more in there
