So the other day I get to work and go to shut off my car. Well I pull the key out but the car is still running! I turned the ignition back on and off....nothing. SO I left the car running to tell my boss I had to take the car home. I get back and there iscoolant spilling out and shit....I look and it seems my car hates to idle. It was backflow from the radiator. Once I moved the car the temps went back down. So I drive the thing home and park it...this time when I turned the key it shut off. Any ideas? Obviously an ignition problem...but where
