Steve, constant, persistent bleeding from the top of the radiator is my current recourse. I've tried all the trick jack-up-one-end of the car methods, and IMHO, NOTHING works as well as simply bleeding a refilled radiator over the course of several days. I do use a special plastic filler funnel made by Lisle that literally clamps onto the surge tank neck and holds 1/2 gallon of water for the initial fill & start-up.

I once replaced our rad, filled it, got a massive air lock in the pump when the engine was started, so I bled it twice more that day. Next day, I bled it again (more air) & we left for 'Vegas. That night after an uneventful 450-mile drive at highway speeds, I found yet MORE air so I bled it a third time in the hotel parking lot. Checking a 4th time before we left 'Vegas to come home, I finally found no air.

I believe 'some' air is partially soluble in tap water; think of burping a water bed- the same phenomenon shows up over months as micro-bubbles of air slowly condense into bigger ones that can cause trouble with marginal cooling systems.
