Freeze plugs are actually very thin wall steel cup shaped pieces pressed into holes in the bottom/sides of the engine.
Once they start leaking, that means they are rotting out and will only get worse.
They can be replaced by regular persons and replaced with a rubber plug. It's smaller than the hole, has steel plate on both sides with a bolt through the middle that's tightened to increase it's diameter, sealing up the hole.
Only hard part is getting the old plugs out. I did mine by shoving a screwdriver through the middle and prying them out (they were that rotten).
One plug, I had to use a punch and knock in one side to turn it sideways in the hole then pry it out.
