To change the alternator in a Lexus LS400, first disconnect the negative battery terminal to ensure safety. Remove any components obstructing access to the alternator, such as the serpentine belt, and unbolt the alternator from its mounting bracket. Disconnect the electrical connectors and remove the old alternator. Install the new alternator by reversing the steps: secure it in place, reconnect the electrical connections, reinstall the serpentine belt, and finally reconnect the battery terminal.
