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.
Remove serpentine belt. Remove alternator. The bolts that hold the tensioner on are under the alternator.
If you're standing at the front of the truck and looking into the engine compartment the tension pulley is on the left side about half way down.

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
To adjust the belt tensioner on a 2000 Dodge Caravan, first, locate the tensioner pulley. Use a wrench or socket on the tensioner bolt to rotate the tensioner away from the belt, which will relieve tension. While holding the tensioner in place, you can adjust or replace the serpentine belt as needed. Release the tensioner slowly to reapply tension to the belt once adjustments are complete.

Loosen the tensioner pulley. The tensioner pulley will slide to the right. This will loosen the alternator belt. So it can be removed.
You unbolt the old one (one bolt) then fit new. Now refit the belt.
To replace the belt tensioner on a 2000 Oldsmobile Alero with a V6 engine, first disconnect the negative battery terminal. Use a wrench or socket to relieve tension on the serpentine belt by rotating the tensioner pulley, then remove the belt from the tensioner. Unscrew the mounting bolts securing the tensioner, and remove it from the engine. Install the new tensioner by reversing the process, ensuring the serpentine belt is properly routed before reconnecting the battery.
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.
