To replace the alternator on a 1993 Lexus LS400, first disconnect the negative battery cable to ensure safety. Remove the drive belt by loosening the tensioner bolt, then detach the alternator's electrical connections and mounting bolts. Once the alternator is free, install the new alternator by reversing these steps, ensuring all connections are secure and the drive belt is properly tensioned before reconnecting the battery.
