As stated in the link that I included (and read the same thing on other 
pages), there seems to be an issue with Dex-Cool when:

- - the level gets too low
- - the car isn't used very frequently
- - thorough cooling system flushing isn't done

Perhaps I didn't flush the system the proper way?  I installed the Prestone 
Flush and Fill kit on the E30, with a hose attachment inserted into a heater 
hose, and reverse flushing the system so that everything comes out of the 
radiator neck.  The drawback to this method is that the system is being 
flushed with cold water from a hose.  Alex used a different method (which I 
also found while searching the Dex-Cool links today), so maybe my f**kup 
caused the problem?

Anyhow, I seem to have no problems with non Dex-Cool systems, so I'll stick 
with it!
