Very bad overheating. We replaced two radiators. Replaced four thermostats, one reservoir, one water pump. Still overheating very bad water spills out very fast. Overheating very bad after a few miles. AC use to work but since over time overheating no AC at all and heater does not work. Help, thank you.

It looks like one problem has caused an even larger one. You may have already repaired the cause of the original overheat but the fact that you overheated it that severely has now caused severe internal damage like a cracked head or blown head gasket.

I would remove all the spark plugs and do a cooling system pressure test for a long period of time and see if any coolant gets into any of the cylinders or for that fact leaks anywhere.

Make sure you are installing the thermostat facing the correct way with the spring facing the engine side.

Thank you for taking the time. I'm not sure if it's facing the right way.I had a guy help me out but I'm gunna take my chances an go to a real mechanic. I've been having so much trouble with my vehicle. Now I've been having transmission issues I think I tried to drive or even in the small streets you know just accelerate to at least 30 miles per hour and it takes awhile for it to catch up or you could feel the tug or just moves real slow and it just revs the engine and it takes awhile for it to catch up I think it's transmission problems I'm not too sure and also I've been having oil leaks here and there. If it's not 1 thing or another but I'll check. Thank you
