Radiator Air Release valve
04 silverado 5.3L
Hi guys, im about to do a radiator drain/fill and im curious, is there an air/pressure release valve of some sort that will allow me to easily remove any air from the coolant system after doing a drain/fill?
Or am I being overly cautious about this, and these particular radiators are very simplistic in design and fool-proof to drain/fill (rarely the case)
Also any tips for getting air out of the system is greatly appreciated.
Edit2: does anyone know if when replacing old anti-freeze if a "flush" with flush fluid is suggested in addition to simply draining old fluid and replacing with new?

Here is what I believe to be the radiator drain valve. I watched a prestone radiator "flush" video that appeared to use a gasoline GM truck for the instructional vehicle.
The shot is super zoomed in, does anyone know its general where-abouts in the engine bay or whether this is actually a picture from a GM Truck, the video said some vehicles may not have one and it switched to this picture, which may or may not be from the truck they were demonstrating on.
