Bob, I think you totally misunderstood my atitude about this.  I realize 
that it SHOULD  be there, I WANT it there, I'm not redesigning anything, 
and don't in any shape, form, or fashion claim to know more than even a 
shitty mechanic or engineer about this.  BUT 1) the engine is in.  2) I 
live in a warm climate.  3) I don't have the hardware 4) I don't have the 
luxury of the image in my mind of removing the thermostat.  5) I've been 
working on this engine for several months and need to get it on the road, 
get the garage cleaned up, and move to another house.  6) There are a few 
other very needy jobs to be done on this bus.

As you mentioned in another post just today, we must pull the engine out 
for many reasons, and fairly occasionally. 

 So, my dilemma, is:  

Take the engine out now, go through the hassle of getting all the parts 
(and with the suppliers I've dealt with so far, this IS a hassle), figure 
out how to install it, etc. etc.

 OR

Wait until the next time I need to pull the engine, have more time and 
less pressure, and do a good job?  

A real mechanic, of course, would not be in this position in the first 
place.  But I am (in this position, NOT a real mechanic) and want the most 
practical solution, all things considered.

The last thing I'll be doing with this bus is racing!

One day at the office, my pants split up the back (fortunately I was 
wearing underwear that day!).  I didn't go home to change, that would have 
taken too long.  Instead I endured the snickers,  used a safety-pin, and had 
the pants fixed right when it was practical to do so.

Hey, I'm not a statement-making kinda guy. I like to be as practical as 
possilbe.  If the thermostat is important enough that the lack of it will 
damage my engine in the next 20-30k miles, I'll pull it and fix it.  If 
it can wait until then without appreciable damage, it would be best, all 
things considered, to wait.  

You've helped me a lot on this whole rebuilding project, and I hope I 
don't seem ungrateful by this post.  I just feel like you misunderstood 
my position and attitude. I'm not the know-better-than-the-engineers guy 
you put on me with this message!  :-)

Thanks as always,

Mitch
