I completely understand the annoyance of not using the proper terms to describe devices. I probably am the most aggressive corrector of others at work. The problem for me is when the OEM's published term does not agree with the actual function of the device and general used terms for the industry. Thus I am at fault for using descriptive terms instead of published names. As for the general used terms for the industry, I am not automotive, but the same devices used in a car cooling system are used in other industrail systems that I am more familair with and adding more confussion when I use those discriptive terms.
My car 5177 did not have TSB #8 article #61. However it did have the earlier superseded air bleed. I was also curious about the effectivness and inspected my tubes and surpressid to find the small tube stabin to the 1 1/4" radiator outlet tube was just flush with the outer diameter (and just upstream of an elbow) making it questionable as being able to provide any ability to vent the upper section of the radiator tank.
I have not read any of the TSB (I guess I need to find a copy of them somewhere). Do you recall which radiator side tank was stated in TSB #8 ariticle #61 to be used for bleed? I have question George P about his cooling drawing (that I plagurized for mine) and he confirmed that the reversing side tank was chosen for a reason versus the outlet/inlet tank. And that reason would be the flow induced head would be greater and thus assist venting/bleed flow.

What is the original location of the factory "expansion tank" in the car? Is the cap 7" higher than the cap on the "swirl tank"?
I don't remember for 5177. I have noticed that in photos that some engine cover pannels have a hole cut above the tank and others do not. I have not checked my engine cover yet
