Question about 2001 Buick LeSabre
There is a single serpentine belt. This belt as with all such belts is held in place by a belt tensioner. This is basically a small pulley hung on a short arm. Inside the arm is a coil spring. It's this coil spring that give the tension to your serpentine belt. In order to change the belt it is necessary to wind the the tensioner up until the belt is loose enough to remove or in your case to reinstall. You do this by placing a socket on to the bolt (see picture #1) in the center of the tensioner pulley. I believe it is a 1/2" socket. Remember two things about this first the coil spring inside is heavy duty and second the more leverage you have on the #1 bolt the easier it will be to release the pressure and move the belt on or off. So the best combination would be a 1/2" drive and socket. If you only have room to get a 3/8" drive and socket then try using a short piece of pipe to increase your leverage.
Another thing to keep in mind is the new belt will undoubtedly be snug even with the tensioner pulley retracted so you may need a third pair of hands to help.
Please let me know if you need any further help or if the tensioner pulley I used in the image is different then yours. It shouldn't be but better safe then sorry.
Also please take care when retracting the tensioner that the socket is on the bolt completely. Slipping off can be dangerous when fingers are in the way. Just in case it's best to use a 6 sided socket instead of a 12 sided because 6 sided has less tendency of slipping off.
Hope this helps.

A drive belt routing diagram is needed when replacing a drive belt to help simplify the installation process. The problem arises as there are many different ways a drive belt can be configured. In this configuration the belt length will vary not allowing the belt to be installed. Also alternative configurations could turn a particular accessory the wrong direction, creating more problems. Always reinstall the drive belt in the exact configuration as the previous belt to prevent these problems. Always use high quality replacement products to avoid premature drive belt failure. If a multi rib drive belt fails it must be replaced immediately to avoid such situations such as engine overheating and loss of the power steering system. Whenever a belt replacement is required inspect the pulley condition to ensure there are no sharp edges on any of the pulleys, this will cause the belt to shred and fail. Confirm that all pulleys are free from debris such as small pebbles, these pebbles will cause the belt to pit and significantly impair the belt performance. The belt tensioner plays an important role to the drive belt performance, if this tensioner is weak it can allow the belt to lose tension allowing the belt to jump and skip. This condition will result in noises such as squeaking, chirping and ticking.
