To replace the alternator on a 2003 BMW Z4, first disconnect the negative battery terminal to ensure safety. Remove the drive belt by loosening the tensioner and then disconnect the wiring harness from the alternator. Unbolt the alternator from its mounting bracket, carefully remove it, and install the new alternator by reversing the process. Finally, reattach the drive belt and reconnect the battery terminal.
