u gotta open the radiator cap when the car is cold and start up the car and let the car run with the heat on full blast, then u start seeing water jumping up n down in the radiator, thats all the air pocket coming out

but how do you know if u have air in the heater core?

and if u know u do need a radiator flush, flush it before u bleed it
