The 2nd gen car that's dead in my hangar is dead because I got dependent
on the 'raise the dead' buzzer that went off when the sensor *in the
overflow tank* sensed low coolant. When the upper tank on the radiator
cracked & lost coolant while driving, the overflow tank still had plenty
in it & I never got the buzzer.

Good point, but I'm ahead of you on this.  My hope is to get an expansion tank mounted high enough to be a gravity feed into the engine. 

This brings up a potentially significant point. Most folks say to use
system pressure to detect leaks.

That was my plan before, but since I'm using Evan's NGR-R, I plan to run a zero pressure system.  I figure this will slow the loss if a leak should develop. 

I'm waaaaay late heading to the hanger, but I just thought about an old aluminum air/oil separator that I have at the hanger.  I'm thinking it might make a good expansion tank/sensor vessel.  Made a note to dig it up and look at it. 

I'm off.

Rusty
