Low coolant light and car overheated at idle

I was at the drive in sitting at idle listening to the movie on my stereo. I had to sit at idle because i have 2 amps hooked up to my system drawing 900 rms. All of a sudden i noticed steam coming from under the hood and shut my car off. The temp gauge was at max and the car was hot. I popped the hood and let it cool down, then added water to the coolant reservour. I noticed some coolant leaked out near the reservour down on the body and frame. There was no coolant by the engine or flung around like when a water pump is leakin. I was wondering if you guys have any idea what happened or what I should look for to be broken. After i added the water and my car cooled down, I drove home without any problem.


Also the low coolant light comes on everytime I shift at high rpms (its an automatic) but the coolant is never very low at all, maybe 6 oz low.

my low coolant light comes on EVERY time i put im foot in the accelerator, or make a sharp turn, if it was your water pump you would not have driven home without any problem, are you sure your radiator fan is kicking on??

or thermy? take that water out as well and put in antifreeze

not sure about the fan, probably wasnt but i dunno

fan relay, all fluids are changed and fixed

the coolant light is normal , mine stays on for a bit everytime i take off or let the engine wind above 4 grand

i had the same problem with the low coolant light coming on when accerating and sharp turns.added some coolant and light hasn't been on since.
