[Vwdiesel] hill climbing

I don't find myself idling to the point of the cycling the cooling fan
very often, though this morning I did and I am pretty sure I'm not
getting more than "a tad above" that level when climbing the hill on
90-95 degree days. At this point, I am not too concerned about the
temperature. I'll still check out the air filter soon. It's been close
to 2 years but well under 10K miles since it's been changed.
I may have been waiting too long to shift to 3rd. I'll experiment over
the next few days and see how it goes.
I noticed yesterday on a different road to the top (twistier with a stop
sign right at the bottom of the hill, so slower speeds) that in 2nd I
could accelerate up to where the 2 dots are on the speedometer (43 mph),
but when I then shifted to 3rd, I couldn't maintain that speed and
slowly fell back to around 35 mph where I felt like it needed 2nd again.
Do y'all think it is best to just keep it roaring along at high rpm in
2nd and forget about trying 3rd?
I've also noticed the Rabbit doesn't have much engine braking at all
(unlike my 1.8T GTI). I remember a discussion of this phenomenon a while
back (something to do with manifold pressure and throttle body
restriction in gas engines, I think).
Has anyone upgraded brakes while still keeping the 13" steel wheels?
Thanks everyone for the suggestions. Gives me something to think about
on the commute.
