Freeze plugs are generally pried out and pounded in, although some are available that seal by squeezing a rubber piece between washers. Use 2 wrenches to tighten these. All generally available at auto parts stores.
The real problem is often getting to the leaking freeze plug. Some are on the lower sides of the block with plumbing and accessories blocking access. There are also some on the rear surface of the block, which usually require separating the transmission from the engine to replace.
