Question about 1993 Mazda 323
Try this, test your cooling fan make sure is in good shape, id would take it out and test it by running 12V to the fan at the plug. I would not to use adjustable thermostats, use only OEM parts when it come to thermostat, spend a little to bring it back to stock, drain all antifreeze and fill it up 80% antifreeze and the rest water. change out your engine coolant temp sensor 32 bucks and auxiliary switch 43 bucks with new one. keeping the vechicle engine in normal operating temp required all the fuse, relay, sensors to work. your coolant temp sensor tells the comp when to turn on the fan when it reach above normal, to cool it down, if it faulty have of the time it wont run.

I have had a similar problem.Check all of your Radiator and Heater hoses for leaks. The cooling system doesn't need to lose much coolant to create overheating problems. If you find no leaks -check that your bottom radiator hose isn't sucking flat and restricting coolant flow.
