Marv, great, just let me know about the cost.

DexCool? Really?  EVERYTHING I have heard about that stuff is terrible.  If
I have the story right, Ford or GM was putting it in the cars thinking they
would have a long life coolant but it ended up ruining a bunch of radiator
and a few engines.  I have even seen an add from a lawyer trying to find
people who's radiators were ruined by DexCool.  Of course the OEM maker
stopped using it.

I don't know anything about its ability to cool, maybe it would work fine if
you change it regularly.

Anyway, hurry up and finish messing with that thing so you can get back to
your project  :-)
