Chirping sound at iddle

Hello everybody,

I have a good one here, I have this chirping sound when my RX its at iddle and cold. I thought that it was the belt, so, I put some belt dressing but the sound didn't go. I'm guessing that is a bearing from the alternator. Anyone had this problem before?

Thanks

Can you twist the belt a full 90degrees, if so it is too loose....

I had the chirping, had the belts replaced, and it went away.

I'm not saying that tightening the belts won't also temporarily cure the chirping; but, if the belts are over 5 years old, I'd just spring for new belts.
