Agree that it's most likely the serpantine belt
My 2011 needed a replacement. Became noisy when accelerating, and was most abundant when it got wet (when it rained or after I washed the Jeep).
Pretty cheap replacement and with your 2012 (that's what your profile says you drive), even if that turns out not to be the cause, it definitely doesn't hurt to get a new belt on there
Okay, I'll be the dumbass of the day. I still have no idea which pully-pullies to buy. Do I replace one? All of em? Ive'never replaced this stuff before. Just want to get it right. I'm not intentionally trying to be a PITA
well I am not there listening to your engine so I can't say. pull the serpentine belt and spin the idler pulleys. open the hood and look inside the engine bay and pinpoint where the squeal is coming from. If it is beyond your ability you might just take to a shop. I have found mechanic stethoscopes are cheap and work great but again unless someone is there who knows what you need to replace. it could the the water pump making the noise.
Thanks for the advice. I am capable of doing the work myself and prefer to do so. I also thought of the water pump. I'll take your advice and remove the belt and check the pullies for noise. I appreciate your time and thank you for your help.
