It's funny too, because that's not even WHY freeze plugs are there. It's just chance they got that name. Their correct name is CORE PLUG because they were part of the casting process. They were never designed to be pushed out by freezing coolant or water. They install way too tight for that.

Right, and water doesn't freeze in a way that would make a core plug work as a freeze plug. The water will get below 0° C and remains a liquid until the block can't contain the pressure of the expansion anymore, then it flash freezes and expands instantaneously, which causes the block to crack. It would take a miracle for that flash freezing to happen right where the core plugs are, and only where the core plugs are.
