A friend of mine let her 240 idle with the ac on for about an 1.5 hours. When she got back to the car it had stalled and she said it was smoking. After it cooled down a bit she started it back up and she says it runs fine. All the fluids are good but the car now overheats when driving. Thats about all the detail I can give you at this point. Anyone know why the car might have stalled or have any advice. I'm hoping it wasnt because the engine overheated to the point where it froze up. Thanks.
