Strange sque

[LCHMOOM]

Hey everyone,
I'm hoping to get some advice on a persistent issue. My engine makes a squeaking sound when it's cold.
I’ve disconnected the belt and replaced the fan clutch (not running anyway)
Still hearing the squeak, and it’s driving me nuts. What's next? Water pump?
Any insights would be appreciated!
Thanks!

does it increase/ decrease with RPM?

does it increase/ decrease with RPM?

I don't think so, at least not obvious.
The bracket bearing will spin no matter if the fan is engaged, so it could be the bracket as well. any ideals to diagnose?

Some people tell me it's normal sound from the valvetrain, but it will decrease when the engine warms up

Check the timing belt pulley and water pump. It could be going out.
