Shit happens....
I am sorry about your Mazda.
Are you SURE "they" have changed
the cooling liquid never ever?
Did not you get any warnings before damage?!
After that, did you leave the thermostat
out of your car = uninstalled = eliminating
it happens never again?!
The safest way is to NOT limit your cooling
system by the help of thermostats or flaps.
But if you still like to do it, which way is safer?!
If the thermostat is jammed in closed-position,
you should notice it before take-off. I think it is a
normal practise to check engine temp is normal
and it stays there before take off.
And when driving car, many people stop their car
when temp gauge is coming close to red...before
damage.
One fact: many "extras" are some kind of risk also.
(Flying) life is full of alternatives. One has to make
best choice suitable just for him. The water thermostat
is one of my choosing...

Well, since you asked..
I recently had to replace the thermostat in my 1995 Mazda Miata (OK,
that is a trifle older than 10 years). Since the thing failed CLOSED I
also had to replace the radiator which burst from the pressure built up
when the engine overheated (which implies that the pressure relief
feature of the radiator cap also did not work as intended). The car has
been maintained per Mazda recommendations.
As for failing in the open position, consider that it normally cycles
with engine temperature and therefore can jam in either the open or
closed position.

Vaughn,
I cannot be absolutely sure but NORMALLY
thermostat design itself leaves it fully
open in failure situation.
Who knows ANY broken thermostat in
cars (younger than 10-20 years)?
Problems may occur if the coolant liquid
is NEVER changed.
In cars most people never do it IMHO.
Just like brake fluid, it should be changed
regularly (let=B4s say once a 1-3 year
to remove moisture and small obstackles etc).
May I suggest you to go some car spare shop,
keep it on your hand and look at it carefully?
Regards, Raimo

I would be very inclined to go with a water thermostat, but I have one
question. If it fails, does it fail closed or open?
