A little backstory: Basically i forgot to put the radiator cap back on when I put water in it and when I drove it for a few miles, the car stalled out on me. Somebody had told me beforehand that the car was overheating cuz it was dripping water while on the highway, but I couldn't see the temp gauge get hotter so I thought I had just overfilled it. When it stopped, i couldn't get it started again even after I tried filling it up with water. Only when I jumped it could i drive again. However, besides having a hard time starting the car, and besides the belt squealing like crazy, the temp gauge goes up passed the halfway mark when I drive for more than a few miles (yes it's got water). I

I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.

you should check you altenator and get it tested.

it is a safety feature so your motor doesnt go boom
do a code search look up how on yahoo also get a code reff sheet there too

first i would purchase a new radiator cap 15 lbs 16 lb capacity cost about $7..then you must let car cool completely...now check radiator coolant level.. top off if it needs it. Now install new cap..let car warm up normally and after it get to normal temp range or higher put hand on upper radiator hose..it should feel hot and when you squeeze it you should feel a slight back pressure..this will mean that the thermostat and water pump are working correctly. if not either the thermostat you purchased is defective or your pump may not be working properly.
when you use just water in an engine the boiling point becomes 212 when you add the correct amount of antifreeze, depending on where you live, the boiling point will go up to 240 degrees. Make sure you put in the correct amount of mix.50/50 will usually work well. sometimes when a gauge does max out like that it could just be trapped air. if after you checked all this out and no air is trapped in the system, i would think that you may have a bad temp sensor. let me know if this helped thanks.
