A thin wall deep 19mm opr 3/4 inch socket works nicely.  I just tired it to
be sure.

If 'T2' means Temp Sensor II, and 19mm was mentioned..
and AC compressor being somewhat in the way ..
with those  hints it can only be a 1.9 2WD wbxr.

the same sensor is used on syncro's ..
but the AC compressor isn't near it of course.
