Quick Alternator pully install question I have my asp underdrive pully and overdrive alternator pully sitting here and I want to throw them on. I know how to put do the crank pully but is the anything special I need to do to remove/install the alternator pully. I havent made an attempt at it yet other than just looking at it and seeing what size socket goes on the nut. Do i need an impact wrech or anything or will the nut just unscrew without any difficulties. I normally would just go and get working on it but I am fairly busy today and dont want to get hung up on a fairly simple install. (I did search so dont bash me) Thanks.

Anyone? I am in the middle of it right now and it looks like you need to use a 24 mm wrench and an allen wrench. I unfortunately dont have a 24 mm wrench only a socket
to get that alternator pully off, you'll need an impact wrench! There is some crazy tool that you can possibly make, but it'll take 2 seconds with an impact wrench. The problem is the nut is free spinning with the pulley and that's where the torque of the impact wrench comes in to play. I've seen someone post some tool they've made to hold the pulley in place while unscrewing the nut. Just get an impact wrench. You'll thank yourself in the end.

Thats what I figured. I guess I will have to make a trip to the hardware store. Do you keep the belt on the pully so you'll have a little resistance or is the impact wrech enough by itself?
i dont think you would get enough resistance, but an impact worked fine for me.. hope you get it figured out, kinda hard to hold the allen with a socket on there, and finding a wrench that will reach in.. best of luck to you!
