Car wouldn't die just because the fans (radiator fans?) don't come on, unless Malibu has some complex ECU that shuts the engine down when the temp' gets too high...?
If the car is overheating and the fan isn't coming on, you could have a head gasket problem. Is there air in the radiator? With a cold engine, find the bleed screw (one of the top corners of the rad') and unscrew it bit by bit until either air or coolant comes out. When coolant comes out, tighten it back up).
