My '01 ST developed a loud screech at 16K. I couldn't pin down the source,
even with a stethoscope. I 'thought' it sounded like it was the idler
pulley, so I replaced it. It was quiet for about a month and then the noise
returned. I then replaced the tensioner pulley, which seemed to cure it.
About 6 months later the noise was back. I discovered that if I sprayed
water( I actually used windex because it was handy) on the belt, the noise
went away for a few seconds. It's been about two years since I replaced the
belt and all's been well, ever since.
BTW, the belt showed no signs of wear or glazing on the grooved side but the
back side was a bit shiny.
