Well… sounds like a belt squeal when i give it gas but horribly loud and constant.

I just did a water pump replacement and now when i press the gas it sounds like the belt is squealing. It’s a brand new belt. I saw online that my pulleys could be off or something could be seized but i’m lost. Any ideas from people who have worked on this engine? 3.0L 2001

What engine?

What engine?

2001 3.0L sorry forgot to include it

 

[O No 3.0!]

Possibly a seized tensioner pulley or idler pulley. Or maybe alternator.
Take the belt back off & check them 1 at a time. If one is seized it will be black most likely.

Water pump replacement? Bad bearing in the new one? Are ya sure the belt is routed correctly?

This would be my first check

Also could be the cam sensor/oil pump drive. If it dries out up top it squawks and squeals something fierce as is galls up the aluminum housing Then it seizes and you loose oil pressure. If the noise is at the back of then engine....I would put money on it being the oil pump drive.

It is at the front. stops when I spray wd40 on the idler pulley. I just replaced the alternator, idler, tensioner, and water pump, the squeak goes away for a while and randomly comes back.

I would take a long handled screwdriver or long pry bar or something at least 2 and a half, 3 ft long, and stick it onto something close to 1 of the pulleys and then put my ear to the other end of what ever it is I'm using and let my ear be my eyes and ears both

I would then move what ever it is I'm using to another spot and see if I can tell a difference.

I would keep moving it around until I figured out where the noise is coming from.

If it's doing it after you did a bunch of work you almost certainly put something back together wrong somehow.

If you hit the idler and it shut up you found your problem
