It is also important to make sure the system is holding pressure before bleeding. I had a leak, and did not ever hear a hiss when uncapping the radiator. Once it was fixed the pressure hiss (from uncapping)came back.(good)
Knowing that you have pressure in the system ensures that you will not suck air in when you open the bleeders.
I would get water to overflow out of my reservoir while trying to bleed the bleeder screws when there was a system leak.
