Evidence at this link
Car is a Honda Fit 2008 GD1 with a new serpentine belt (GATES) and a new tensioner pulley (it's generic).
I got this weird noise at EXACTLY 1500 RPM (no A/C) no matter the gear or if it's during acceleration or deacceleration. It started two weeks after belt/pulley replacement so I suspect is the pulley.
I took the car to the mechanic but it didnt make the sound then. A few days after is back again.
Im going to replace the pulley with a Honda one, but what do you think it could be?
