2004 Suburban Cooling System Bleeder Screw Location

[Domano 68]

Getting ready to drain and fill coolant on my 04 Suburban 1500. To prevent getting air bubbles in the system, the cooling system bleeder screws should be opened when refilling the coolant reservoir. I just don't know where they are located. Any help would be much appreciated. Thanks.

Refill and burp it with nose up...way up. Otherwise, air hides in the rear heater core and lines.
