Hey guys. i have this insanely annoying squealing noise when it is cold out like under 55degrees and seems to go away once the car is heated up. i have a audio clip and could use some help in figuring out what it is. it seems to be coming from the back bottom part of the motor. thanks in advance

 

sounds like your FEAD. there is tsb for it, had it written down but can't find it. do a search for FEAD noise.

 

I already replaced the idler pulley a couple of weeks ago and that did not fix the noise. I also replaced the belt tensioner assembly as well.
