Freeze plugs are located on the sides of the engine block to allow for the expansion of the coolant if it should freeze. Without them the engine block could crack. They do not normally have to be replaced unless they begin to leak from corrosion or external damage.
There are multiple freeze plugs but mostly down both sides of the block. If you have a leaky freeze plug, you need to find out which one. Some are easy to get to and some are impossible without removing the engine.
Were are the freeze plugs
At minimum, removing the engine mounts is required to access the freeze plugs.
Depends on the location, but usually. Expect the task to be very difficult. Some freeze plugs are behind motor mounts or in front of engine cradles. Some freeze plugs are behind the flywheel, which requires removing the transmission for access. Removing the freeze plug is only one part of the task - installation is as difficult as removal, if not more so. The freeze plug must be installed properly aligned or it will leak. Freeze plugs are interference fit, so some means of applying pressure to the freeze plug must be found. Usually this means putting a socket inside the freeze plug or on the lip of the freeze plug and hammering it in. This requires room to swing the hammer. Don't forget to place the freeze plugs in a freezer for several hours before installation. This shrinks the freeze plug a tiny amount, and every bit helps.
There are quite a few reasons why your bottled water appears to freeze after removing it from the freezer. This is because it did freeze.
Running it without a freeze plug it will run but can and will cause permenant damage to the engine to to the amount of antifreeze you will lose Running it without a freeze plug it will run but can and will cause permenant damage to the engine to to the amount of antifreeze you will lose
It is impossible to do it you have to pull the engine
no withou a freeze plug the water will escape the engine and cause it to over heat.
The engine will leak out coolant/antifreeze from the freeze plug area. Freeze plugs can be replaced, it may take a lot of work to replace one but they are made to be replaceable. It is not advisable to drive any vehicle with a blown freeze plug.

There are two, both on the backside of engine near flywheel. Can be accessed by removing engine or dropping tranny. I know, I just left the shop for the same reason.
