2001 International 3000 engine sound

My engine just started making a weird sound. Didnít notice until I got out at a stop. Itís loudest at the very front. Below is a link to a video where you can hear the sound. I point to the general area itís coming from... but itís basically just from right inside the front.

Is this a bad sound? Sounds like maybe a fan??? But I know nothing about Diesel engines....

DT-466 engine
Allison 2500 transmission

That's a bearing going out or a slipping belt making that noise.

Thanks guys. We’re hanging tight at a truck stop for the night and taking it to a mechanic in the morning...

guess we’ll be delayed as we flee civilization...
