May repeat this procedure once or twice/until no air bubbles are seen with the spilling coolant from the bleeder screw.
Use a thick absorbent cloth near the bleeder screw so you don't spill coolant onto engine bay.
I personally would not run the engine with coolant expansion tank cap open. The bleeder screw is meant to be used for bleeding the coolant system.
Hope this helps!

Thanks! I think that's what I am missing. I was opening the tank reservoir cap instead of bleeder screw. I will try that and report back
