ok so a while ago me and my friend changed the alternator on my car and afterwards there was this really loud noise coming from the alternator belt. So we tightened it and the noise went away. But after driving around for a while the noise has started to come back, only it's not as loud as it was before, but it's still annoying.
So does this mean that I just havn't found the right setting that it needs to be at?

The belt can make noises if too loose or tight and also if out of alignment. As if a washer was not placed properly when replacing the alternator. Try the tension adjustment first. Do no use belt dressing. You may need a new belt, I would have replaced it with the alternator.

I would agree with the diagnosis that you did not tighten the correct bolts or didn't tighten them securely.
I would guess, as with most alternators, there are two bolts to tighten, one at the arm where the belt adjustment is made, usually a curved piece, and the other where the alternator attaches to the engine, usually a long bolt and a nut, that is the pivot point. keep pressure on the alternator to keep the belts tight as you tighten the bolts. Don't over do it or you can damage the bearings in the alternator.

When you changed the alternator it might have been smart to change out the belt at the same time. Recheck the alignment of the alternator belt and see if it lines up straight. Tension is what most people adjust, but the pulleys are not aligned right there are additional stresses to the belt that will premature wear it out.
Also correctly torque the hold down bolts. Hope this helps.

More than likely yes. Your not adjusting it correctly,Or Your not getting everything tight after the adjustment. You need to keep the alternator adjusted while it's being tightened whether it be will an adjustment assembly with a tension bolt or the other kind you need to use a pry bar to keep the tension on the alternator while tightening
the slide adjustment bolt

the actual belt cant make noise...its rubber. the noise is coming from the tensioner pulley or the alternator itself. try and wiggle the tensioner pulley and if there is any side to side play then the bearings are gone out ands that's your squeak.

Typically it will squeak if it's not tight enough, You didn't mention weather or not you replaced the belt when you did the alt. So I will assume that you didn't. personally it's my policy to change it need it or not. Odds are while the belt still looks ok it may be deteriated enough to make it squeal,

no it prabably means that the belt streched a little. try tightening it again and spray "belt dressing" on it ($2.99 in any auto parts store). that should fix your squeak
