Whine coming from the engine

This started on Friday as I was leaving work. What's strange is I drove it early that day to get lunch and the noise wasn't there.

It sounds very similar to an alternator whine coming through your stereo but I have determined that not to be it for my case. You can definitely hear it when you start it up but gets lower when I shift into drive or reverse. When I'm driving I can't hear it anymore probably because it's getting drown out by road noise. I can't pin point exactly where it is coming from but it is coming from the engine bay and more so on the left side. I checked all fluids and they're ok.

Any ideas?
 
Left side when looking from the front of the car with the hood up (passenger side) ?

If it's clearly from the engine bay and not under the car or from the back of the engine bay (ie: from the transmission), it's probably just a pulley or idler bearing. The cold weather tends to bring out the squeals as winter starts.

At this point it's like asking "My computer is making noise". 🙂

I think it's the one in his Sig


But if it's not and in any case it's a Ford then it's prolly the power steering pump 😛 😉

 
Even on the Lexus, it could be the PS pump going out. It's almost 10 years old and while fluids could be fine, the pump could be shot.
