I also thought the valve piece that allowed the fluid to pass had to be
installed in the right position (90, 180, 270, or 360 degrees within the
pipe) to work properly? You'd have to try it in any of those positions to
see which one works.

There are three types of heat transfer that need to be accounted for.
   Conduction
   Convection
   Radiation

The foil on dynamat is an effective way to reduce *radiation* heat transfer
if it is placed in the engine compartment so the foil faces the engine and
other sources of heat.
