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.
