Any home store will have what ya need in the plumbing section.
 
Actually the factory plug is a 1/2" square 'female' plug. Assuming you are asking about the NON A/C block off plug.
The temp sender is a 1/8th inch thread, and that hole is 1/8th NPT.

I have some new 1/2" plugs.
 
I have a/c car

Are you talking about the brass piece that a mechanical temp gauge sender screws into?
Yes the temperature sending unit screws into the nut and the nut screws into the water pump housing
