Only hear it after it warms up and it gets worse with some load (a/c on or sawing the wheel back and forth). It goes away at anything above idle. I thought I had it isolated to the tensioner pulley. Changed it; didn't help. Have since changed both idler pulleys and the belt; no change. Everything felt smooth, 'normal' with the belt off. I can't seem to isolate it with a stethoscope. Any ideas on which bearing/accessory would be most likely? Thanks! Put some comet kitchen cleaner dust on the belt. If the noise is gone its the belt.
