Hi,


I've Toyota Sienna 03, sorry I posted in this forum. I got much help from this forum

The belt make some squeal noise when cold start, for about 10 seconds, then back to normal. I can tell the alternator belt has some slack. so I think to tighten it up a little bit. unfortunately the adjusting lock bolt （B) is stripped.






I assume the Adjusting Lock Bolt is attached to the alternator, so I am thinking the best option is to remove the alternator put it on the desk and it give me better room/option to address the stuck broken bolt.

I have couple of questions:

1. With the broken bolt still in the slot (see the picture), is the alternator removable?
   
2. once alternator is out, I am thinking about using vise grip to turn it. Is this a good enough tool?

3. I see some comment about drill, heat. Can you recommend some tool please
   

to save all the trouble, if don't want to try all of this DIY, is it drivable to nearby shop (with no locking bolt and adjusting bolt in place) ?

Thank you very much!

Remove bolt A and see if the alternator will come out.

Probably? As long as the bolt isn't seized in the alternator.

What else is on that belt? If it's just the alternator and A/C compressor you could drive it a short distance with the belt off and be okay. I would not drive it with the belt on and that bolt broken.

That doesn't look stripped. Looks like the head snapped off.

Definitely do what Mr. Potato above said. See if you can finagle the alternator out after taking out bolt A. Alternatively, if B is on its own bracket, see if you can finagle that bracket out with the bolt.

Finally take it out. took 2 days, an 30+ cold/heat, and pray.
