Freeze Plug Replacement? on 1994 Chevrolet 1500 Pickup

I recently had a freeze plug fail on the rear passenger side of the block. Can I repair this at home or is a mechanic required? The truck overheated. I stopped to add coolant. I noticed that the radiator did not stay full and that the fluid was leaking out near the starter. This is a freeze plug problem?

there is a couple good vids on youtube demonstrating how to replace freeze plugs. I had one go behind the motor mount on the driver side. It was a pain in the ass, but it is doable. All of the vids show the engine completely out, but it may not be necessary to go that far. I was able to remove the nuts and bolts of the motor mount on the drivers side, the one nut on the passengers side mount. then the two bolts holding the tranny to the frame. Then jacked up the engine, knocked out the motor mount and did what the guy on you tube said.
