Sounds like the bearings on your idler pulley or another pulley ate it.

MA-12 page for setting proper belt tension. What I'd do if it were me would be to remove the serpentine belts and try to spin the idler pulley and other pulleys by hand. Youll find out in short order which one needs replacing.

Fan clutch maybe?

step one: INSPECT the belt. don't just tighten it arbitrarily
step two: remove all belts and spin the pullies by hand. when you find the one that feels like gravel, you have your culprit.

Thats what my a/c compressor sounded like before it started blowing sparks out the clutch and locked up.

to reiterate

check how all accessories feel like by hand
turn them off 1 by one to see which one is making the noise
theres a chance an accessory is about to fail


inspect belt visually and by touch

also
never overtighten a belt
Its worse to over than under. I always leave them a little loose them tighten if necessary.
and I recommend
always carry spare belts and other consumables like fuel pump and spark plugs, a spare coil pack, spare igniter maybe
and when it comes to s13 sr20det engines always keep a spare power steering and alternator handy minimum

Yeah, I change my fuel pump and spark plugs on the side of the road all the time.

I've changed fuel pumps in my s13 a few times on the side of the highway, or at a track event.

Ehh I get carrying one failure prone show-stopping sensor or something, but when you're carrying a spare car in your glovebox.... maybe just expect to hitchike to autozone if your car breaks?

a fuel pump for this car to get you home is like $23.13 shipped and it weighs around 1lb and takes up almost no space.

So yeah Im going to carry anything that cheap and that light and I recommend anyone with the type of vehicle that could shit a performance part at any second do so as well

you dont need to carry expensive parts just the basics, Often I won't carry a spare tire either (due to lsd concerns) just a tire plug kit and air pump.

Part of the reason I started carrying so many of these things was because back in the day I would have to tune a couple of cars like mine in a day (sr20 setups or whatever) and it was very handy to have a spare igniter, coils, plugs, etc... on hand to help out with diagnostics and often I would be leaving this or that behind to help someone out. I weighed out and made a 'kit' of sorts with various necessities, most of which fit into the 240sx quarter

Bad alternator shouldn’t cause a no start if your battery is still good and charged. What is it doing? Crank no start? No crank? Just a click? could be a separate unrelated issue or check if you forgot to plug something else in, ie. MAF sensor, loose ground, etc

[luke100]

lol my bad the battery died. was just stressing at the time. still doesnt sound quite right with the new belts and no belt on the idler pulley but ill look at that tomorrow.

[luke100]

This is with no belt on the idler pulley

Could it be a bad PS pump?

Still sounds like the fan clutch to me.

[luke100]

I have tried without the fan and it stilll sounds the same unfortunately
