Do you have to remove the serpentine belt before removing the alternator?

No vehicle is specified, however, in all vehicles I have seen and/or worked on, the serpentine belt must be removed from the pulley that spins the alternator. NOTE: Some vehicles have another, separate, serpentine style belt that runs the a/c compressor and may have to be removed to remove the belt running the alternator. (Complete removal is not necessary unless the belt needs to be replaced.)
