That web site was interesting.  I think whether we all recore our
radiators (or regularly check our hypothetical water jacket screens)
some kind of after shut down water circulation system is a good idea.

Of course, the website doesn't list which one fits a V12, and it seems
like a lot of cash for a couple of clutch/pullies and a dc motor. 
Although there is no way I could fab something like that.
