This is the after picture. This is after we found out that we failed to order ALL the parts we needed to get thermostat flappers working, tried and failed to rig it, tried to make our own, ordered the correct ones, and waited another week for them to arrive from Sunny Southern California (they're the little silver pieces on each end of the crosspiece). In this picture, the fan shroud is upside-down.  The thin rod

Tracy is holding in her left hand will go down through the cylinder head to the thermostat (a little round brass accordion thingy). The thermostat is mounted under the head in the path of the air after it is blown through the cylinder head.     So...when the engine is cold the spring you see in the middle of this photo makes sure the flaps are closed. As the air blowing through the head gets hot, the accordion expands which pushes the rod in Tracy's hand up, and opens the flaps letting more air through until they're wide open and the car is overheating anyway. Actually, Gene Berg says that these flaps DO help in cooling by helping to direct the air where it needs to be. Lets hope so.

The next thing we noticed was that there was this big gap around the oil cooler so we made this sealing spring-flap out of aluminum flashing.          We have since learned that a guy who knows way more than me posted instructions on how to make this part. Apparently there IS a part that's supposed to be there but you can't buy them anymore. Here's the link: http://www.type2.com/ rvanness/sealfram.htm

There was also space around the sides of the cooler. We used high quality weather-strip to seal it. If anyone out there has a more elegant (permanent) solution, please let us know.
