I just installed a supposedly correct sending unit for my on again, off
again temp gauge and it reads above half after driving around the block a
couple of times on a 23 degree Celsius day. Is this normal? where should the
needle read at "normal" operating temp.?

I'm thinking a got the wrong sending unit. The new one came in a box: Brand
FAE, number 32110 followed by a small circle mid line.
