To replace the alternator on a 2004 Chevy Malibu, first disconnect the negative battery cable to prevent electrical shock. Remove the serpentine belt by loosening the tensioner, then unbolt the alternator from its mounting bracket. Disconnect the electrical connectors and power wire from the alternator, and then install the new alternator by reversing the steps. Reattach the serpentine belt and reconnect the battery cable once everything is secured.
