Just replaced it myself you gota take the alternator off loosen two bolts that hold the tensioner on and pull it out.Don't loosen any bolts on the powersteering under the tensioner.Remember to disconnect the battery first.
You unbolt the old one (one bolt) then fit new. Now refit the belt.
To replace the tensioner pulley on a 2000 Oldsmobile Intrigue, first, disconnect the negative battery terminal for safety. Then, use a wrench or socket to relieve tension on the serpentine belt by turning the tensioner pulley counterclockwise. Remove the old tensioner pulley by unbolting it and then install the new pulley in its place, securing it with bolts. Finally, reattach the serpentine belt, ensuring it's properly aligned, and reconnect the battery terminal.
Yes, on a 3.3 or 3.8 the serpentine belt pulley does come off the tensioner arm but the bolt is left thread not right handed.

alternator on a 2000 Pontiac runs off a serpentine belt if its loose then chances are ur serpentine belt is worn or stretched or your tensioner pulley is bad or the tensioner itself..alternator bolts stable does not move like the old setup.
Look on the passenger front side of the engine, you will see pulley attached to a short arm with a square hole. That is the tensioner and tensioner pulley
Loosen the tensioner pulley. The tensioner pulley will slide to the right. This will loosen the alternator belt. So it can be removed.
The Tensioner is spring loaded-use a long wrench on the center of the pulley 2 release tension-DON"T UNBOLT anything-IF it doesn't feel springy then find the bolt in the center of a (the) pulley that is.
98% of the time it is the tensioner or idler pulley. With engine off take WD 40 with that little plastic tube & spray the back side of either one, idler or tensioner pulley, not both. Take a drive & if you still hear the belt noise then it is the pulley you didn't spray. The tensioer pulley is replacable on most dakotas. When you remove the belt the tensioner should have strong spring action & move smoothly. If it does then just replace the pulley. Some places will try to sell you the whole tensioner.
There is one 15mm nut on the back side of the tensioner. You have to get at it from under the vehicle. It is just below the end of the exhaust manifold. It is fairly easy if you use a long extension and a flex socket.
I just did one today for my uncles 2000 Leganza 2.2. The trick is that the belt goes around the tensioner then the crankshaft pulley. It should make an s from the bottom of the alt. pulley to the tensioner then to the crank.
You cannot adjust the belt tension on a 2000 dodge grand caravan. This vehicle is equipped with an automatic tensioner. If tensioner is frozen or will not hold the belt tight, it must be replaced.
