You've definitely got some things going on with the codes there, not all (any?) of which could be caused by a bad pulley bearing.
So I'd reset the codes and see what comes back. You may as well work through them, largely independent of the noise. And it could be that you've got a hose that fell off and is causing many things, including the sound.
But now that you know the noise can happen when parked, it brings anything driven by the belt much more into the prime suspect area. Be very careful with the stethoscope and spinning things like the fan - it can be dangerous.
LOL, if all those codes are real (they come back after reset), this might actually be a time when a parts cannon approach has a good chance of fixing something. 
But really, I'd start working through them. The sound may be one of the toughest things to track down, and maybe you'll fix the sound as you chase down the codes. Pay attention to when the codes come back. Check often. |

All good advice. The codes are quite daunting to me. I think I want to start out by changing all the bearing laden components along the accessory drive belt then see what codes I have left and whether that horrible noise goes away. Another person, or maybe even several, have mentioned that at high mileage (mine is approaching 180k and I drive it pretty hard) that it’s a good idea to change all those parts out anyways because if they haven’t gone yet, they will soon.
My only issue now is choosing the right overhaul kit. I’m probably just going to purchase whichever seems most comprehensive and turn it over to my Indy mechanic. I just can’t picture me not losing my mind changing out something like 7 or 8 components and two belts in my driveway in the middle of the Texas summer and without a lift… that’s just not going to end well.
There’s so many iterations of kits out there. If anyone has any recommendations, much appreciated. Leaning towards this one at the moment:
