If I take the belt off the pulley spins rather freely but, I have put on two properly adjusted new belts and they all squeak. When I let off the gas and look at the belt it looks like there is like back pressure so it flops around. I can feel the pulley on the alt and its warmer then all the other pulleys as if it was the one causing the issue. Is there a way to test this? Or should I just replace it? Traditional tests will not work since it outputs correctly I just think its becomes hard to spin under load.

hmm it seems to me that if its squeaks, then of course the belt is not adjusted properly.
if the alternator spins freely and make no noise the it should be good as long as its charging properly which in your case seems like it is.Comment

how are you adjusting your belt? how tight do you make it? you need to have them pretty tight because they will strech over the next 100 or so miles and start squeaking...I like to adjust them to where there is barely any play in them at all....if you are maxing out your adjuster then you might have the wrong size belt too....good luck"I can imagine no more rewarding a career.

i am having the same problem right now, because just replaced my alternator. It is squeaking because it is loose, i dont know why but i keep breaking my adjuster screw everytime i try to stretch my belt.Originally posted by ChIoVnIdCa
anywhoo the pulley is warm bc of the friction from squeaking, so you dont have to test anything just tightened up the belt as much as possible, if it still does not work, then you have on the wrong belt wich i doubt

FWIW, often times a local shop will look at the belt tightness for free. When I replaced the brushes on my alternator (which you know involves removing the PS pump and alternator), I took my car to the shop that does many of my repairs, and they confirmed I had the belt tensioned correctly. If you have a shop you use for major repairs, take it there...Comment
