Squealing Noise at Idle

[Flightmaster127]

Recently I've been noticing what sounds like a squealing noise coming from my car while its sitting at idle after its fully warmed up to operating temperature. The sound is coming from the pulley side of the engine/ passenger side. It sounds like belt squeal, but I cant seem to source the exact location.

2014 Civic Si sedan with just over 7k on the odometer. I will try to get a video of the noise after work today. Wondering if anyone else has this issue, or knows what's causing it.

Some possibilities for a new-ish belt to squeal ........ Loose/spray-on cleaners/light fly-wheels/and last but not least... cold weather.......

Hmm. I did notice that I always seem to notice it when it's cold out.

Maybe the belt isn't tight enough so it slips when it's really cold. I'd ask the dealership to check your belt tensions.

Doesn't it auto tension?

 

[Bulkybear]

Yes it does, I'd be willing to bet it's a pulley or pulley bearing. So it still could be the tensioner.

The temperature warmed up on Sunday and I happened to notice that the noise wasn't present. The temp has dropped back down again today and the noise is back.
