Why do thermostats need to have the "top" side up? They have "top"
stamped in them but I don't see any reason why one side needs to be
up.

The temperature sensor of the thrermostat has to be in the hot water. If
you install it backwards, with the sensor toward the radiator, the
thermostat will never open. BTW, don't be confused by "up". Some
thermostats mount in a vertical plane. The "up" means "toward the radiator".

Because there is a wax pellet that expands as it heats. If you put it in
backwards, the wax would sit on the "cold" side of the coolant flow.
You'd have to get a really hot engine to get it to open, but once it did,
all that heat would keep it open! Actually it probably wouldn't open,
but I never tried. Even if it did open, if it closed later because it
was a really cold day, it would not open again easy, and you'd get a
really hot engine again!

They may not all be this way, but the ones that I have looked at
have a air valve to bleed off air pockets... of course for this to
work, the air valve must be up top.

Am I thinking of the right thing?

You want to know a good thermostat. Rolls Royce. I am not being
humorous. It is just like any other thermostat. EXCEPT, that it has
several holes about 3/8" drilled around it. They are filled with what I
think is some lead alloy that melts if the engine coolant in the block
gets too hot. Here was a company planning ahead! Everything can (and
with time will) fail. Why not plan for it. I've never heard of any
other company doing this. Probably too expensive, but why can't the
aftermarket come up with something similar???
