Belt question.......with pics

So only a few weeks ago I replaced the alternator belt because it was squeeling. Put the new one on, tightened everything up the way it should....and now a few weeks later its worse than the old one was. So I was gonna pull it off to look at the wear on it and I noticed that the belt was sitting real low in the V-pulley on the alternator. So I compared its width to that of the new PS blet I got and the PS belt is just a smidgen wider. I put the PS belt up against the alternator pulley and noticed that it doesn't sit as low. After pulling the belt I noticed that it was wearing a lot on the tips of the V and has put a real nice polish on the inside of the alternator pulley. So do I just need a wider belt? Look at the pics and tell me if it looks too narrow. Could there be a deeper reason behind me goin through this belt so quick?

Here is the alt. belt that I think sits too low......


and here is the PS belt on the same Alt pulley

You'll love this:

Try sprinkling some baking soda on the belt while the engine is running. This will cause the squeal to go away.

Re: Belt question.......with pics

I already tried tightening it up a little, loosening it a little, and belt dressing. I think the problem is that its riding on the point of the V and not on the sides and is wearing out real quick and then no good. Does this make sense?

Re: Belt question.......with pics

To me that looks like it's riding about right in the pulley. Could the pulley be worn?

Looks good at the top

Don't look right at the bottom.

Maybe it's the camera angle, maybe it's the way you're holding it.

Try a different brand. It shouldn't ride deep enough to touch the bottom of the V.

Its the angle the camera is at....it sits at the same depth top and bottom as you see in the bottom of that picture. I thought it was really low too, so I'm just gonna buy a new belt and hope it works.

Re: Belt question.......with pics

Humm... I'm wondering if the alternator is good. One sign that an alternator is dying is wearing belts. The engine is turning and the alternator is trying to pump out electrons but the load is too much for it. The alternator has a load, and it can't keep up...and there alternator is seen as a drag.

Hence a squeal from what looks to be a perfectly good belt and the sides begin to glaze.

When it's squealing, remove the alternator field and see if the squealing stops. That's a clue!

Barring that, take a look at the other items driven by that belt... if they are compromised... the same thing happens.

Re: Belt question.......with pics

just my 2 cents worth here, but as a general rule the top of the belt should be flush with the top of the pulley groove(just a shade low is ok too, but the belt should NEVER contact the bottom of the groove),yours appears to be worn out, my guess is if you look at the groove, the sides will be dished out somewhat, try a new pulley....
