Question about Dodge Caravan
Apply a small amount of dielectric grease to the ribbed surface of the belt with the engine off. Just a dab will do. Start the vehicle. If the noise gets better or goes away its the belt. If it persists, remove the belt making note of the direction of travel.
With the belt removed rotate all of the components the belt turns by hand. If any feel unusual or make the noise you hear than it is bad. if everything is good start the vehicle with the belt off to confirm the noise has stopped (do not run for more 5 to 10 seconds). then reinstall the belt so that it rotates in the opposite direction than when you took it off.
Did the noise stop?

Spray a little of belt dressing on the belt to stop the squealing or just change the belt. You change the belt to see if that stops the problem because if you change the tensioner, it's best to change the belt to. Most likely the belt is the problem. Just don't spray any slick lube substance on it.

personally it is a really tight area to work in and if you are not experienced with mechanics i would get a pro to do it as if you misalign the pulley or break any bolts on it you are really screwed try jew the mechanic down as it is only about a 1 hour job if you know what you are doing

SOURCE: Belt noise
this may be a belt alignment issue, check the relative position of all the pulleys to one another, there may be a recall on this issue, contact your local dealer.

Sounds like your serpentine belt has become stretched over time and needs to be replaced. One of the pulleys is going to be spring loaded and placing a wrench on it and pushing or pulling(gently but firmly) will give you the direction to loosen it off. This belt tensioner is non adjustable .It either tightens the belt enough or it doesn't hence the squeal.Good luck.
