Need to replace alternator belt on 2000 dodge neon, but need pulley diagram

over p/s pulley,down to a/c pulley ,up to crankshaft pulley ,under tensioner pulley

Hope this helps ??

You will have to go to the tensioner pulley and put a wrench on that bolt and apply presure in the allowed direction and take the belt off...look first to see if there is a diagram of how the belt goes back on if there isn't write one down before you take the belt off...might be a good time to inspect the belt for cracks and replace as needed.

Good Evening, I would hope it is the belt or the alternator first because the belt tensioner is a bear to replace. I would recommend taking a better look at your belts first 80% of squeaking and squealing are from dirty, and old belts. And while you are changing it out you can spin each pulley by hand and see if there is one specifically making noise and go from there. Hope this helps.

Get the replacement belt, and then note the pulleys that have smooth finish, and note the pulleys that have the grooved finish.

Just 'thread' the serpentine belt, one pulley after another alternating between the smooth and grooved until the last remaining pulley is the tensioner pulley.

Use the breaker bar to allow the pulley to accept the belt, and you're done.

loosen the center bolt of the a/c idle pulley, then on top of pulley you will see the adjusting bolt, turn to loosen to remove belt, after new belt , tighten to where you have 1/2 play on elt then tighten center nut of pulley

Can be a host of things, mainly pulley bearings. The most common is the binder pulley. Having worked for Chrysler/Dodge/Jeep i can tell you that it's one of the main problems for all dodges, not just neons. If the pulleys are fine, maybe the belt is too loose and slips on the pullleys causing the noise. Also, it could be the new alternator itself being defective. I've seen plenty of alternators coming new straight out of the box and having busted bearings, or the internals hitting each other or the casing, preventing the alternator to spin freely. Other than that, it would be best to have the car checked out by a mechanic.

that would be your power steering pump not a pulley

The power steering and A/C belt is tensioned by a tensioner pulley. Mine went bad and was "screaming" I thought it was the power steering pump and I replaced it only to find that it wasn't the problem. I couldn't find any bolts and deemed it too much of a problem for me to replace at home. The shop had to drop the engine and transaxle assembly from the engine bay in order to get enough room to replace the pulley. The problem with many FWD cars is having enough room to work so if you have to replace it, the engine has to move because you only have about two inches of room otherwise.
