had the same problem and it was a coolant seal. i ran my car for about a month with the buzzer going. when i got my turbo motor in the guy said the engine is still in good shape, just needs a rebuild. so you prolly have minor damage done.

 

if your overflow tank keeps filling, its most likely coolant seal (engine rebuild time)

 

Sounds like a coolant seal to me.

 

#1 Never ever ever use anything but the Mazda OEM thermostat. Anything else is a "will fit" and is not designed for actual use in a rotary.

#2 not clear what you replaced. You said
But then you talk about the rad cap too.
