Mazda was right for the first time! damn. You probably blew a coolant o ring. Replace your water pump with this tool real quick and pressure test. http://www.pineappleracing.com/cooli...estercspt.aspx

Make sure your overflows not cracked. You have to bleed the cooling system thoroughly when you refill otherwise you get air pockets in the engine that cause overheating.

What were the 3 responses you got?
How many miles on the current motor (not the chassis)? and what kind of motor(reman etc etc)?

Dont start it again until youve diagnosed the problem or youll just cost yourself more for a rebuild.

if your running coolant and not water, smell your exhaust. it will smell sweet, and not like burnt gas if a water jacket is bad. this is a free not so accurate way to test.

but to be sure... get the tool listed above.

Rule #1 of FD ownership: the moment you think you have any overheat or coolant system issue, shut the engine off and stop driving the car. Period.

What did the 3 different garages say? Were any of them rotary shops?

Based on your brief description, bad coolant seals are very possible. Engine rebuild time.
