This is what I remember from T2 director's cut: https://www.youtube.com/watch?v=yiBHj8Xs4sg (at 0:21).
When I saw the theatrical cut it always confused me how John could tell who was the T1000. And it also annoyed me that Arnie shot the frozen T1000, seemingly only speeding up his thawing.
In the director's cut you see that T1000 is actually damaged, but not damaged like a non-liquid robot would be. It's not losing mobility (control) of an arm, but instead losing control of its morphing functions.
It's complete genius that was (almost[1]) entirely cut from the theatrical cut. It's ridiculous that the edit it out.
[1] There's exactly one "flicker" of T1000 metalliness in the theatrical cut. A small remnant of a genius idea.
