Unhappy Help! Coolant leak (Evans waterless)?

I bought my first 3rd gen about 3-4 months ago, so I have to admit that I have little experience with rotories in general.

I went to start my car this morning and the idiot light for the coolant came on along with the buzzer. I went to checked the cooland and to my surprise, I can't find any. Everything look empty, although everything looks a little wet. I can't be certain of the last time I checked the coolant, but it has always been fine when I have before.

The radiator looks okay. The lines, from what I can see seem fine. The engine bay is pretty clean so I figure that i should have been able to see any coolant leaks.

The AST has some coolant in it at the bottom, but it has a cloud of brown flakes in it. It reminds me of that bars stop leak, but I can't imagine a newer radiator having to need it. Is this normal?

My car is a 93 with a fluidyne radiator, aluminum ast, and is said to be using evans waterless coolant (its yellow-orange i think). The mazda oem engine has about 24,000 miles on it. The temp. has been staying between 90-110 deg C.

What do you guys think is going on? Where has my coolant gone? What do I do next?

How low does the coolant have to be for the idiot light to come?

Can I add water to an evans waterless system to check for leaks? (i don't have any extra coolant at the moment and i'm stuck here at home).

Could there be a more serious problem with the engine?

Or is it just that i'm a complete idiot and coolant in rotories slowly disappears?

One way or another i really could use some help.

Thank you

No!

Probably OK for Evans Hmmm

Well in a 0 pressure system it shouldn't go anywhere but soundlike a leak

How low does the coolant have to be for the idiot light to come?
About 6 oz, sensor is at the bottom of the filler neck


Ca I add water to an evans waterless system to check for leaks?
ABSOLUTELY NOT!!!!!!

Could there be a more serious problem with the engine?
Maybe

Really just check your radiator upper and lower, also your turbo hoses. I bet it was one of those, hate to see someone put stop leak in the cooling system though. I wonder what it would do to the evans.
