Weird engine Squeal help?

I had a similiar situation - alt bearing

i dont think its the timing belt cause it didnt do this in warm weather it didnt start doing it till it started getting cold here. i probably wont be able to work on it or a while now since its -20 celcius here now and the garage i use isnt heated.

I am suprised no one has suggested the power steering system.  PS fluid is hygroscopic, and needs to be changed much more often than people usually go (I do a flush every 3 years).  Since you mentioned that is sometimes starts when you go hard lock with the steering, I would try replacing the fluid.  This would also explain why it gets worse when it gets colder.

i just changed all my belts on my 1.6td jetta but it still makes the noise that an old or loose belt would the alternater was rebuilt before i got the car. It does it sometimes when i make a sharp turn. also when im driving if i psh the clutch in it will stop any suggestions?

This would go right along with PS fluid.. sounds like an older ford lol!

putting the clutch in reduces engine rpm's and thus reducing PS pump rpm as well.

disengaging the clutch makes engine RPM rise, its turning less rotating mass. it doesnt add more load to the engine slowing it down.

Not if he was driving around at the time the clutch was disengaged, then RPM would drop.  And as 8v-of-fury said, the first thing I thought of was my 90's fords that used to make that squeal when fluid was not maintained.

ok, well thats considered decelerating. i hadnt thought of speed yet.

[8v-of-fury]

yup in my my post i quoted a quote that the OP said while driving pushing in the clutch makes the noise stop. so it is engine Rpm related. because the trans, and axles maintain the same speed you are driving at, unless your hitting the brakes.

its gotta be belts. or alt bearings.
