That's correct.  But the car's temperature was fine the whole way.  
Then as soon as the otterstat popped out and much of the coolant 
departed the system - then it started overheating.

And this is exactly the type of behaviour I was seeing before I 
embarked on removing the otterstat...  The car would only overheat 
when it was idling or stuck in stop and go traffic.  As soon as I 
got out onto the open freeway, or a long stretch of road where I 
could get the speed up, the temperature gauge would come back down 
to the quarter mark.

I did indeed try this test at home after popping out the otterstat 
and putting it back in.  I turned the car on and let it idle in the 
driveway for fifteen min.  The temperature needle made it all the 
way up to the halfway mark and I never heard the fans come on.

The other thing I tried was the air bleeding trick.  I've seen at 
least two different methods of doing it - one where you just open 
the screw and let the air out, and another where you need tubes and 
buckets, running water and coolant.  I opted for the simpler method, 
but I think after all is said and done, I will try the somewhat more 
complicated one...  :-)
