The factory steel ones do occasionally rust through. There's no repair, you need to replace the plug.

First, drain the block, there's a pipe plug about at the center front/rear, just above the oil pan. These are usually blocked by rust, so you may need to open the hole with a screwdriver after the plug is out. This keeps you from getting drenched with antifreeze in the next step.

I use a 3/8" extension, and whack the freeze plug on one side (it will take a good whack, get your trusty BFH). They usually will rotate 90 degrees, so half is in the block and half is sticking out. Grab it with a pair of pliers or vise grips and pull it out. Square a new one up, and tap it in. I believe the block uses 1.5" plugs. I prefer to use brass so they don't rust.

If clearance is an issue, you can get ones that are 2 washers with rubber between that expand when you tighten the nut. I don't recommend them, because eventually the rubber breaks down and the problem comes back.
