First post, long time lurker. Chugging noise at idle that is quite loud on my Ls coming from the fan area. I checked the fan clutch and it seems fine (even tried another used one). I looked at the fan bracket and the bearing was fine and it didn't seem to have any play. I just changed the idler pulley, and pressed a new bearing into the tensioner pulley. The noise is still present and I found a video that sounds exactly the same. I do get a separate droning noise when the AC is on, but i was going to press another bearing into the clutch. I've spun all the pulleys and they sound and feel fine. Just thought someone else would know what I'm dealing with. Thanks in advance.

Sounds kinda normal.
