Default Corvette Procharger Guys... belt issues?

So, I recently acquired an LT4 Vette with a Procharger set up on it. Full inter-cooled kit with no substitutions as I can see. It developed a bit of a squeak when cold that would tend to go away and did increase with RPMs. always sounded like it was coming from the front of the motor. Anyway, hit it with some belt dressing and the squeak went away, but my son then described the car as making a "marbles in a can sound" over 2k rpms.

Dropped the belt off the pulleys, and the bearing in the idler seemed suspect. So after removing the alternator, idler pulley, and power steering pulley, out she came.

Had a duralast tensioner, the exterior surface of the pulley definitely had some crap on it., and a duralast idler... hmm.

Anyway, put it all back together now it's a new sound... idle is dead silent and if you give it a rev, belt squeal over 2500rpm now.

I am thinking at this point, it is best to just replace the belt. Would have done this first, but it seems almost impossible to get it out around the pulley of the Procharger because the mounting rods encase the pulley. Any tips/tricks? As you can imagine, the instructions from parocharger for installation is pretty much "route the belt and install". Not exactly the most helpful. Just liek the service manual with the tensioner, yea remove the bolt and pull it out. Sure... except for no instructions on what needs to be removed to actually get the idler out of the engine bay

Was looking at that last night.

I got the old belt off. Had to remove two of the SC mounting bolts and spacers. Tonight will be trying to figure out how to slip it in and reach from drivers to passenger side to grab the belt. Taking the Radiator out might do the trick... but let's hope not. Maybe just some heater hoses.

So... for the belt it required pulling the power steering reservoir off it's mount, pulling the radiator hose, 2 of the bolts of the Supercharge and one coil mounting bolt. Oh, and the arm of a 9yo to reach across the front of the engine and get it to the drivers side. Never had a belt be such a pain.

Back on the road now.
