If more tension doesn't help, I'd replace the belt and be sure to clean the pulleys with brake cleaner or a degreaser. Old belts tend to dry out and loose their grip.spacecad3t wrote: Sun Jun 07, 2026 3:45 pm Following up here as I finally got around to testing the belt squeal. I spray water on it, immediately quiets up. Must be too loose still? Or maybe galled from old pullies? Im going to try and add a tiny bit more tension this week and see.

Thanks Tom. I should have probably cleaned the pulleys during the Alt/Belt change, as it is a new belt, and if its oily now, then yeah- I'll have to put another new belt on.Tom wrote: Mon Jun 08, 2026 6:51 amIf more tension doesn't help, I'd replace the belt and be sure to clean the pulleys with brake cleaner or a degreaser.
