2.5L engine whine

[Marc_986]

With the ignition issue resolved it is time to discuss a sound my car is making. It is a pretty loud whine from the engine compartment. Related to engine RPM. I'm pretty sure I've checked once without the belt and the sound persisted. AOS has been swapped out since (as it was going bad), but that didn't change this noise. Engine starts and pulls ok, no smoke on start-up or driving. Basically it is just this noise.

As it is difficult to describe I found the same or similar noise on U-tube, but unfortunately without any answer to what it was. So input greatly appreciated;

Does it have any CEL or pending codes? Not sure if a standard obd2 reader shows all the codes so maybe try to find an iCarSoft Por or relevant good reader ?

Since you already tested it without the belt, that helps narrow down the possible causes. At first i thought it may be (any) pulley, water pump or anything closely related
