Mark, I can't see why you think that. If there's a leak anywhere, and if
the level of coolant goes down 2-3 inches, then the coolant temp sensor at
the end of the block gets uncovered by coolant and the combustion chamber
there ceases to be cooled and that temp sensor will cause a temp gage start
climbing (now reading CHT instead of coolant temp) and an alarm from the
engine monitoring system will go off. So, I should know there's a leak
before the engine block empties and the seals are damaged. I don't see how
the plumbing I described makes the system more susceptable to uncovering the
water pump inlet. If the leak is so bad the level falls below the inlet of
the water pump, it ain't gonna pump, period, any system design. Help me if
I'm missing something.

David,
Won't a system as you have described stop pumping much sooner in the
event of a leak, or low coolant level? It seems to me that low coolant
level
would allow air to be sucked into the return lines to the wp and cause the
wp to loose its prime, thereby shutting down your cooling system. That
could ruin your whole day.
