RE: u/d pullies
you dont need an impact. just some sockets and wrenches should do the trick. all you gotta do is take the belt off, take the pullies off that you are changing, install new pullies, install belt. should take an hour, tops. you might wanna try and crack the bolts/nuts loose before you take the belt off, might make it a bit easier

RE: u/d pullies
Youre definately going to need an impact gun to get the alternator pulley off.
For the water pump pulley you need to unbolt the fan and then the bolts on the pulley. I removed the radiator brackets to make a little more room for the fan to come out.
For the crank pulley just undo the 4 bolts and tap the pulley off to remove it. The harmonic balancer doesnt need to come off.
I used the stock belt.

You might want to keep the stock alternator pulley on because of a lower output at idle, and by changing the crank pulley all accesories will already be using less power by slowing them down, but i dont know your situation or what you have. Def break all bolts loose before removing the belt. You still may have charging issues while idleing running electric accessories but give it a try and good luck.
