There is no tension adjustment. Tension is automatically adjusted by the idler pulley.

Loosen the tensioner pulley on your 1992 Buick LeSabre. Take the serpentine belt off. Put the new serpentine belt on and tighten it down with the tensioner pulley.
Put the proper size wrench or socket on the pulley of the tensioner.Pull the wrench counter clockwise to release the tension on the belt.
Serepentine bels do not have tension adjustments, there is a tension pully That is preloaded with a coil spring in it. If the belt is loose, the pully spring may have lost it tension. Replace the pully assembley.
Use a socket and ratchet on the bolt that holds the 95 Park Ave serpentine pulley. Pull the ratchet to the side and the pulley will swivel, loosening tension on the belt. Remove the belt, install the new belt in the same manner.
put a wrench on the tensioner pully and pull it to release tension on the belt
I have used a socket with a ratchet handle. The ratchet will allow you to get more travel to move the pulley and get the belt off.
Old age Frozen or misaligned pulley
you do not adjust a serpentine belt. the adjustment is done automatically by the tension pulley if belt is loose, purchase a new belt . also check that all pulleys are in good shape before installing new belt
The 1988 Buick Skylark 2.3 liter engine serpentine belt tensioner pulley is held in place with a single retaining bolt. The retaining bolt will be in the center of the pulley. Remove the retaining bolt.

go to youtube and type in ericthecarguy and change pulley
pull the tensioner to relieve the tension and slip the belt over the alternator pulley. The tensioner is a spring-loaded pulley below the alternator. The tensioner takes a special tool that fits into a square hole in the side of it. Or you can use an 18 mm socket on the tensioner's pulley bolt. Follow the decal near the right front corner of the engine compartment to route the new belt.
Use a socket and ratchet on the belt tensioner pulley bolt. Pull the ratchet to the side to let tension from the belt. Remove the belt. Install the new belt ( a helper will make the job easier.) Release the ratchet to set the belt tension.
Best to get a shop manual for this operation, if you have not replaced it before. Usually there is an "Idler Pulley" on many late model cars that is "spring loaded". You "Bias" this pulley using the big nut in the middle of the pulley (usually with a socket wrench) so that the serpentine belt has enough slack in it so you can remove it. Install new belt by reverse procedure. TommyTrouble
Remove belt and tensioner should just be bolted to engine
get someone that knows what they are doing, to replace it the 2 long front engine mount bolts need to be removed to replace serpentine belt
You need to remove the serpentine belt to remove this. The tensioner is the spring loaded pulley that puts the right tension on the belt. It is fairly easy to locate it. I have used a socket with a ratchet handle to offload the tension and remove the belt. You will run out of travel room with just a straight handle tool. Once off, the entire arm or just the pulley can be removed.
There is a spring-loaded tensioner pulley that keeps tension on the belt. The tensioner should have a place to fit a ratchet wrench or breaker bar (may or may not need a socket). The tensioner bar rotates clockwise or counterclockwise to release the tension on the belt. Be sure and note how the belt is routed so you will install the new belt in the same pattern. The tensioner is self-adjusting.
Loosen the tension on the 95 Buick Park Ave belt by moving the belt tensioner to one side. Using a socket and ratchet on the tensioner pulley, pull to the side an remove the belt. Install the new belt an release the tensioner to hold the belt into place.
Maybe $100 tops....
You should not have to remove any brackets to do this. Near the top of the belt run is a pulley on a spring loaded belt tensioner; insert a ratchet or use a wrench to release the spring tension and the belt will come off.
It can cost between $14 and $30 to replace a serpentine belt on a car. The price can raise to $40 or $60 if a person has it done at a car shop.
You have to remove the engine mount next to it, then remove the 4 bolts in the pulley
