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

Well you got me with plug kit and air pump - I just generally think of fuel pumps as a once in a blue moon/200k part. The access panel makes it a roadside job and all, I know.

But I sure like having my car buttoned up like an airplane - if I have to set it down, I expect to bring my truck to recover it. The truck's a fixn' barge, can carry anything it and any other vehicle needs, or transport it.

And if you depend on a vehicle, of any age or type, you pretty much need a second vehicle, you know?

So spinning my idler pulley by hand sounds like this

Is it safe to say thats what the issue is? If it is, would i have to buy a replacement? Or could i ask around locally and buy a used one from someone?

I also span all the other pulleys by hand and they were quiet.

Thanks

I think you already know the answer to your first question. It should be silent or just about. That thing is TOAST.


Why put another used one in there? It's a pulley with bearings. They dont last forever and this isnt a big money part. You could roll the dice or just get the new part and know it's going to stay fixed.

The whole part OEM is less than $100 USD. I'm confidant they make aftermarket versions for cheaper. Not sure what parts stores you have but here's the part number from the dealership; M-11925-65F03

Also make sure you follow the fsm in my initial reply for setting proper belt tension. You can really damage other components and shorten their life by overtightening the belt. The arrows are where you check for deflection.





Also inspect your belts for wear while you're in there. flip them inside out and inspect for cracks along the radius as they bend and for signs of wear. Seized pulleys will damage the belt too. The idler pulley is only for your A/C compressor drive. It's possible to run without that one specific belt but you'll want the one for the power steering and DEFINITELY the one that drives your alternator and water pump.
