BTW, the whining noise that I had just assumed was the power steering pump isn't that at all. It's coming from the other side of the engine and is not the accessory drive belt, as when I mist water onto the belt's contact surface the nature of the noise doesn't change at all. It has to be caused by one of three components:
1) Idler Pulley
2) Water Pump
3) Alternator (bearings)

Some might suggest that I replace the Idler Pulley as it's by far the least expensive possible culprit, which is a pretty sensible argument. However, does anyone have any hard-earned wisdom to toss my way? I hate to just replace parts when my odds are only 1 out of 3.
