2016 Ram Hemi squealing

[Rambm]

Hi, 2016 Ram with Hemi, makes squealing or screeching noise from engine. Noise is not there during cold start up. Does go away for short periods of time. I pulled the fuse on the electric fan that confirmed that is not the problem. Let me know your thoughts.

Idler pulley maybe? Bad serpentine belt? Alternator bearings?

No one can really help you unless you upload a vid of the noise.

I'm assisting original poster with video. Update- Noise is still present at operating temp with serpentine belt removed.
I have heard the sound in person and thought I heard the sound continue for a split second after engine was turned off.

Are you trying to post the video directly here? If that isnt working upload it to Youtube or another video hosting site and then post the link here...

I tried via add attachment. I then tried saving to phone and stumbled onto an option to create a link to video... Tried posting link here and said post not visible, awaiting admin approval.

Here's a YouTube link attempt- https://youtube.com/shorts/vI3YLzxqWC4?si=aFp5EhjFPESXBWGo

When you see that notice, it needs to be approved by someone on the forum staff. Usually someone will be along within a couple of hours to approve the post.

I have a very similar noise I am chasing on a 14 hemi outdoorsman . mine is about 1200 rpms coasting 2 belt kits from napa and its still there . using a stethascope I thought i had in pinned down to idler pulley but was wrong . noise is still there

Alternator or A/C compressor clutch maybe. Definitely a rotational noise like a bearing.

A stethascope will work wonders in finding source.

take the friggen belt off

That sounds like a typical water pump

First thing to do, is disconnect the negative post on the battery.
Then reach under the water pump, you should feel a hole, if your finger gets wet, replace the water pump.

If that does not work ...

Take a couple of pix of the way the serpentine belt goes around the pulleys & remove the belt
start the engine

Rotational: If U pull belt and still have same noise when started, then there is another issue, as rotational internet guessnosis would be wrong since the after listed parts would not be being rotated. Rotational guesses: Sounds like either Idler Tensioner, Lone idler pulley, AC clutches, alternator, water pump.
