I have a whining/squealing noise coming from under the hood. It only does this when it is cold outside, and only when the engine has warmed up. It only does this at lower RPMs. Once the RPMS are at 1500 and above, it does nothing. I have replaced the serpentine belt with a Goodyear Gatorback, replaced the idler pulley, and replaced the tensioner pulley. None of these fixed my problem. I will try and post a video I took while driving, so you can hear the noise. I will not do it at an idle, it is like the vehicle must be moving. Therefore, I am having a hard time locating the problem, since it does not whine/squeal once I have it in the garage.
Please help me figure out what this could be. Thanks
