Noise stopped.
Much wtr direct from hose (not spray bottle) on different pulley and noise stopped. After 30-60 sec noise returned. Repeated this 6 times. The last two listened to returned noise for over 10min and it never stopped or changed...until more wtr.
Unplug alt or turn on AC also stops noise. Screwdrver to ear cant find source.
Free spinning pulleys fell smooth and silent. Although most have some play.
Took car for 1st street drive since noise 1st manifested months ago. Drove for 20 min. Then noise was gone. Only time ever no noise except for 2nd time w\wtr on belt and alt\AC mentioned above.
After street drive let idle for 10 min and no noise. A few days later another 10 min idle no noise. A few weeks later noise present and louder (i have recording). After about 10 min noise volume reduced and was like all previous times. Then after 5 min it went away. Then it returned for few seconds and went away for 10-30 sec or even a minute or few minutes then returned for few seconds. Over and over.
Few week later start no noise, drv for 20 minutes and no noise again
For months every time I ran engine it made this noise, now actually drving car seems to stop it.
150k miles. Belt chnged w\oem about 6 months before.
Thoughts?
