I have just started noticing this noise when I fire up the car in the morning. Chicago + outdoors all night = very cold start. The interesting thing is that now that I've been listening for it, I noticed it isn't there immediately after startup.

I go outside, fire up the car, no noise. I come back outside after a few minutes of letting it idle and this is what I hear.

It almost sounds like a squeaky belt? Definitely coming from the engine bay, sounds like passenger side (i.e. belt side).

 

Might be a pully or something related.

 

i got that same thing when it's really cold. goes away after warms up.. haven't heard it since nice weather here came above 35..

 

I didn't watch the video but i'm going to say timing belt tensioner pully. Had mines replaced under warranty 2 month ago.

Me and 3 other local guys have had it replaced under warranty.

 

I would say a pully, I get a simular noise

 

Yes n00b question but how immediately should I get this addressed? Any danger in just going with it for a few months?

 

mine does the same thing when its cold out, goes away after it warms up

 

Sounds pretty normal to me

 

yea maybe the tensioner pulley need to be replaced
