I have a 1996 SR20DET Blacktop.
The noise seems to come from:
1) Water pump/belt
2) Alternator belt
3) Power steering pump/belt
The squealing noise happens every 15-30 min and lasts for about 1-3 min. If I maintained about 1500 rpm when the car was idled, the noise seemed to go away quicker.
Please see the video.

The noise started from 0:06 and ended at 0:37.
I put some WD-40 on the bearings for power steering pump and water pump already, but the noise is still there.
Do you have any suggestions/comments?
Thanks!
