Why is my serpentine belt continuously shredding?

There is no movement or adjust-ability of any of the components. You may be able to squeeze a few mm's here or there.

Those washers would only move the built guard forward or backward. It would not adjust the location of either the alternator of the power steering pump.

Did the dealership replace the AC bracket?

The idler was at a slight tilt or the belt was at a slight tilt?

Can you take some photos. The only photos you have posted so far are once the belt is shredded and out of alignment.

Gotcha. The previous mention of the large amount of movement in the idler bracket made me wonder.

It definitely did move things. By putting pressure on the power steering pump it was very easy to watch the belt move on the idler, immediately.

They replaced the bracket that mounts the alternator and idler, I don't know if that is what you are talking about.

The belt was at a slight tilt. The idler was straight, but too far back based on the location of the bearing. Pressing the bearing brought the idler forward, so the belt was no longer riding on the back edge.

I will.

I'll add some pics in a few.

That is the bracket I am talking about.

How in the heck did you press and move the bearing and idler together. That is insane. You should not be able to move the idler and the bearing it rides on.

This is what I would do (or have your mechanic do)

1. Remove the belt
2. Unbolt the idler
3. Take pictures of following
a. idler bolt
b. idler washer - front and back
c. idler - front and back
d. AC/alternator bracket where the idler mounts.

You should not be able to move the idler at all. I feel like I am taking crazy pills...

She took the idler off the car and pressed the bearing down so it was riding further forward. Does that make sense? The idler doesn't move.

[Glennda5id]

Did she use a press? Those bearings are pressed in.

she shouldn't have NEEDED to unseat the bearing and shift it, but I can understand the desire to do that.

This is post repairs, with everything seeming to be fine.

If you mean the bearing was not fully pressed into the pulley, that makes sense.

She pressed the bearing so that it allowed the idler to stick out further so that the belt was not coming off the back of the idler. She may have pressed it out, rather than in, and it was not a huge amount of space, but enough to make it ride better.
