If you are talking about literal antifreeze, ethylene glycol, then no, it does not need to be pressurized to work, and the proof of this is that there is documentation of Ford dealers putting ethylene glycol antifreeze in Model As in 1929 and reporting that it worked great.

Yes Colin, however right now it is Summer, and the main topic in this thread is about a Model-A with an overheating issue -and not about preventing freeze cracking.

So yes, Antifreeze mixed with Water can prevent freeze cracking so we all should agree that it has its place for use in a Model-A ....however the suggestion from many, (-both here and on Social Media) is that using a mixture of Antifreeze is better at preventing overheating instead of straight Water. Why isn't this considered misinformation??

OK if that is in fact the suggestion then that's certainly incorrect. I don't recall seeing that proposition in this thread, though.
