So, I replaced my fan belt and idler pulley the other day, hoping to get rid of a bad belt squeak and a wierd noise. Well, thankfully the squeaky noise is gone (that was Sooo annoying!), but the other noise is still here. I'm pretty sure it's the alternator, maybe one of the bearings? When I would twist it with my hand, it would make noise, and all of the other pulleys were silent. I also started the truck without the belt off, and this particular noise was absent. It's kind of a churning type of noise, like water flowing. I figured it was the water pump for the longest time, but I guess it's the alternator. So, the question is, is there anything I can do to fix this, short of getting a new alternator? I'm always an advocate of fixing something small now instead of something larger later. But, if there's no short-term fix, and it isn't likely to die really soon, I'll probably just leave it.
