If the block and radiator and heater core had near-pure water in them and it was a hard-freezing winter where you are, the results could be bad indeed. Ice could have made leaks in the radiator and heater core, both probably requiring a new or used-parts replacement as a lot of small leaks would be unfixable.

And the ice could have pushed the so-called freeze plugs, or some of them, out of the block. Those plugs can be replaced, some if not all of them with the motor in the car. But it won't be easy.

They're a tapered cup-shaped thickish sheet metal formed item, a press fit in the holes in the block. Drive them in with a hammer and short section of wooden dowel. Need to go far enough so they're just flush with outside of hole. Push them too far and they'll drop into the interior of the block's water passages and you'll need to use another.

They can be bought; someone on this site had found a Dorman part number for a size that was just right.

I once left water in a Chevy six too late in the fall and a freeze plug got pushed out; I bought a rubber plug replacement with a little screw in the center that you tightened and it made the rubber fatter so it wouldn't come out. Worked fine.

They aren't actually designed as pressure relievers for ice in the block; they're there because casting an engine block with internal passages in it requires that there be holes somewhere. Then they're plugged.
