Sitting in a parking lot with my car idling....next thing i know i hear a loud "psssssssssssss" and see clouds of white smoke...opened the hood and saw a 6 inch crack on the top of my radiator... replaced the raditator (not completely finished with it yet, it started snowing)... I was just wondering if the crack in the radiator was the only thing i needed to be concerned with......or could there be something else that might have happened too (not concerning the radiator)?? ANY HELP WOULD BE AWESOME!!
