What happens when you loosen a serpentine belt?
If your vehicle uses the alternator bracket to apply tension to the belt, loosen the two bolts that pass through the long eyelets on the bracket. As you loosen the bolts, the tension on the belt will likely move the alternator toward the engine and relieve the pressure. Loosen the bolts enough to move the alternator, but don’t remove them.
How do you tighten the nut on a serpentine belt?
Place the socket end of the socket wrench over the wing-nut and turn clockwise to apply tension. It is likely not possible to adjust this by hand, so check your socket set for a socket that will fit snugly over the wing-nut so that you can tighten the nut, thereby applying more tension to the serpentine belt.

Why does my serpentine belt slip in the morning?
Very small amounts of water appear on the serpentine belt in the morning acting as sort of lubricant, causing the belt to slip. This, combined with the beginning of belt material fatigue will cause this sound. It usually disappears once the belt warms up a bit (like 10 to 20 seconds after the engine is started).
What kind of pulley does a serpentine belt use?
Determine if there is a belt tensioner pulley. Depending on the application, your serpentine belt will either have tension placed on it using a movable bracket or an auto tensioner pulley. This pulley uses an internal spring to apply consistent pressure to the belt at all times.
Where do I find the serpentine belt on my car?
