Re: Optimal temperature, radiator cap, etc.

Bob,
  I had a Saab with the window shade at the radiator also.  Volvos at
that time had them, as did some of the diesel Mercedes. Perhaps it was a
cold-country thing.
  It's not just small engines that get cooled by air flowing over them.
Look at any large diesel truck on the highway in the winter. All have a
cover over the radiator.
   My 2.8L Chevy S-10 uses a 195 degree stat.  It comes to normal
operating temp about the same distance from home during winter and
summer. In summer the temp goes to the 195 mark and stays there. In
winter, it goes there, cycles back down as 'stat opens, goes up and down
for 30 miles or so before it gets steady.  WIth 1/3 of the radiator
covered by a cardboard, it runs at a steady temperature.
