Re: Alternator belt is loose
Normally, there would be an idler pulley with bracket and spring or along an adjustable lever along the belt. It is held in place by a single central bolt that should be loosened up, adjusted to provide adequate tension to the belt and tightened.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

as the alternator IS the adjuster for the tension of the belt,it is a simple task of undoing the alternator bolts/nuts and pushing it inwards to fit belt,then pull it outward to tension belt to correct tension...
If the same as my '94 cyl then you tighten the belt by loosening the bolt that the alternator pivots on and the bolt that tightens the alternator to it's adjustment bracket. For my truck this is neither fun nor easy. The a/c and power steering belts having idler pulleys with adjustments on them making them MUCH easier to deal with.
It sounds like the alternator belt or the alternator is going bad. The squealing sound was probably the alternator belt. the alternator belt might need to get tightened or replaced or you may need a new alternator. The alternator keeps the battery charged. When the alternator goes bad the battery can not be recharged. You also should keep the power steering fluid up to par or the power steering will go bad on you.
REMOVAL & INSTALLATION
Fig. 1: A gauge is recommended, but you can check belt tension with thumb pressure
Fig. 2: Loosen the component's mounting and adjusting bolts slightly to remove or adjust the belt(s)
Fig. 3: Push the component toward the engine and slip off the belt
Fig. 4: Slip the new belt over the pulley
Fig. 5: Pull outward on the component and tighten the mounting bolts
Fig. 6: Accessory mountings found on 6.2L diesel engines
Loosen the driven accessory's pivot and mounting bolts.
Move the accessory toward or away from the engine until the tension is correct. You can use a wooden hammer handle, or broomstick, as a lever, but do not use anything metallic, such as a prybar.
Tighten the bolts and recheck the tension. If new belts have been installed, run the engine for a few minutes, then recheck and readjust as necessary.
It is better to have belts too loose than too tight, because overtight belts will lead to bearing failure, particularly in the water pump and alternator. However, loose belts place an extremely high impact load on the driven component due to the whipping action of the belt.
its not hard to replace an alternator,,,there are 2 bolts that hold it in place that you have to take out.make sure you take the pos battery cable loose so you dont short anything out , once you remove the bolts he alternator will move freely there is a wiring harness hooked to the back of it that you have to take loose and then you can pull the alternator off the try.you put it back the same way you took the old one off and when you go to tighten the belt you need a prybar to apply tension against the alternator and then as you keep that tension on therer you tighten the golts to keep the belt tight. thats about all there is to it
you shouldent need to remove anything to replace or tighten your serpantine belt there is two pullys without grooves the one on the left should be the tensioner if you turn the bolt clockwise it looses the belt off so you can pull it off if done right you can take the belt and pull it around the fan then reverse to put a new one back on
