The 2009 Chevy Malibu could experience overheating issues from various issues such as a cracked or failing thermostat housing, coolant leaks, and a faulty radiator fan. Low oil levels can lead to increased engine friction and heat generation. Clogged or disconnected coolant lines may cause antifreeze leaks. A common diagnostic approach involves flushing out the current antifreeze to eliminate dirty or contaminated fluid. Some Malibu owners have found success by replacing the cap on the surge tank, which stores excess coolant between the engine and radiator. Corrupted caps or seals, as well as damaged hoses, can result in engine overheating.
