The serpentine tensioner pulley location on a Chevy Malibu varies slightly depending on the year and engine. However, it's generally located on the
front of the engine, near the
bottom of the serpentine belt system. It's usually easily visible once you remove the splash shield or access panel in front of the engine.
To be precise, you need to specify the year and engine of your Malibu (e.g., 2010 Malibu with a 2.4L engine). With that information, you can find a diagram online (e.g., a repair manual or parts diagram from a reputable auto parts website) that will show the exact location.
