It could be the radiator is bad. There is a plug located on the bottom of the radiator. Unscrew the plug and let the fluid drain, you should be able to see if there is rust or gunk in the water/antifreeze. Then use a garden hose and put it in the hole used to fill the radiator and let the water run.

I have 2002 mazda mpv it keeps overheating when ever am driving, with our without AC. I have replaced gasket, water pump, and things I need to change in the car and yet is still over heating what do I do...

If you already checked the cooling fan system you are a step ahead.
If you have gone through all that you have done. you may have a crack somewhere in the cooling system, external or internal.a mechanic should do a pressure check to test for this possibility

My Mazda MPV 1995 is overheating. I have changed the thermostat and fklushed the radiator. The water pump seems fine. Of note is the bottom hose going to the thrmostat is cold. Does this mean the water...

Nornally the hose will warm up but not hot with a circulating system. the therostae could be installed upside down or be bad. You should install a therostate with a asprin holding it open to circulate the coolant till the cooling system is full and the asprim will disolve as it soaks in the coolant. the air will ciculatre to the top and out and the systrem will be full. the stat will work corectly after the asprim is gone. with air around the stast it might not open and therefore overheat.

You probably never cleaned the cooling system out.

If you have not get it done by pros.

It seems something is blocking the flow. If the water pump went bad you will know. Rarely ever heard a impeller breaks off like you think. The bearings and the seal break first.

Check and see also if the heater valve is working.

As for the over heating even new thermostats fail. Reverse flush is needed or the procan measure the pressure in the radiator cooling system and edetermine if there is a engine pressure problem. Tools and experience is the key in the game of diagnosis.

Engine overheating

The best way to flush it would be to take off the bottom radiator hose and pump water through the fill nozzle after all the coolent is out you can then hook the hose back up and replace it with new coolant.
