Tracy, this has got me to thinking about an alarm system
that would be useful for the coolant pressure gauge.
A simple pressure activated warning light would not be
useful because the pressure starts out at zero and
gradually builds, then during different modes of flight
when your engine cools the pressure would go back down.
Not having flown with a water cooled system yet I don't
know how much it would fluctuate.
Would it be worthwhile to have a small processor
programmed to keep track of engine temps and compare
those to what the coolant pressure should be, then set the
alarm off if they don't add up?

The best advice I can give is to learn the behavior (not just the static
reading) of your coolant pressure gauge and pay attention to any
anomaly. It tells the whole story IF you know how to interpret it.
