I recently notice a high-pitched noise from the engine compartment of my '05 V70R that has ~67,000 miles. The noise is BARELY audible inside if the radio and fan is off, but much more noticeable if the windows are down, especially if next to a wall to ricochet the noise. So I'm not positive how long the noise has been present since I usually drive with the windows up and A/C on, but I think it is pretty new.
The noise is a constant pitch and volume and sounds like a squeal or whistle. It does not vary with engine speed or car speed. It is audible as soon as the RPM's come down after starting the engine and is constant until the engine is shut off. It sometimes seems like the noise goes away for the instant that I'm in the process of engaging the clutch. I noticed this when in the parking lot and just add the clutch was starting to engage, the noise stopped and then started immediately again either when I push the clutch back on or let it all the way out. That said, I don't it is actually related to the clutch directly since it feels and acts normally and the noise is present whether in neutral, in gear, with the pedal all the way down, or the clutch engaged.
Turning the A/C on or off makes no difference; neither does the fan.
I wonder whether it is the serpentine belt or something attached to it, though I can not localize the noise to that area. A vacuum leak was my other thought. That said, in pretty ignorant when it comes to these things.
Any ideas and /or trouble shooting advice?
Here is a link to a youtube video I made - you can hear the high-pitched whine above the clacking of the engine.
