There is a bolt on the lower bracket for the Alternator but that doesnt mean its whats causing the belt to screech... It could be dirt, a worn belt or a worn pulley. Take some greese, vasaline or anything like that, put it on the belt itself or if you wish the pulley and see if that helps, it worked great for my spirit cause i didnt want to replace belt even tho it is a good idea to replace the belt.
Tighten your tensioner pully. there should be a little bolt on one of your pullys.
Replacing the AC belt is probably one of the easiest things to do... Just simply losen the tensioner pulley and remove belt... Install new belt on all the pulleys then tighten the tensioner pulley. Its that easy.
If the belt is riding on the outside of the pulley then the Alternator isn't on perfectly straight or atleast straight enough to keep the belt on... My Spirit did that and it split the belt and I had to get a new belt, and it was cause the garage didnt space the pulley that's on the alternator like it should have been... I don't have an impact wrench or else I would of done it myself and done it right.

Install everything back on the car except for the alternator belt. You are going to need a long socket bar and a 15 mm socket. A socket bar is basically a rachet without the rachet mechanism. It has the square end on it to go into the socket at a 90 degree angle. Set up the belt on all the pulleys except for the alternator. Put the socket and bar on the bolt that is holding the tensioner on and twist it like you were tightening it. This will move the tensioner and give you slack so you can put the belt onto the alternator pulley. Once it's on and aligned, slowly ease off the bar until the belt goes tight. Remove the socket and bar and you are done.
Look at the face of the alternator. Below it is a round thing that looks like a dial. Loosen that nut - 15mm...To the right of the alternator - or if you are standing in front of the car -- in front of the alternator, below it -- is a nut on a threaded rod -- 1/2" socket AND a universal adapter because of the extreme angle of this nut.... This is what pushes the alternator up or down.CCW allows pushing the alternator down ( loosen the belt ) -- andCW brings the alternator back up ( tighten belt )StanFarmington CT
Tighten it or replace it.
Water pump is located below alternator on passengers side
Once you slack the axle, there should be adjusters to tighten up, just make sure the wheel is even, and torque the axle nut back to spec's.
Your pulley system that controls the motion of the belt and the tighness will either consist of 4 or five pulleys, with the Alt, being of course at the top. the very bottom pulley that likey can only be reached from under th car, should be your compressor pulley, the one in the middle, between the alt. and the compressor, should be your water pump with its pulley. Using the process of elimination, you can find out that there will be a pulley left, this is the belt tensioner pulley. It has a bolt in the center of it, it may be either 5/8 or 15 mm. This can be fitted with a wrench, or if you are lucky, a ratchet, and then turned as if you were loosening it, you will see the alt , pull up and it will be tightened this way, you may also want to apply some belt dressing. if this doesn't help , the belt may be squealing for another reason, such as the water pumb may be getting ready to go out or the compressor pulley may be getting loose.
