Yep, that's all you do. Just take the one bolt off. Then pull the pulley, swap over the spacer off the old one to the new one, and bolt it back on. Das it.

That's the one good thing about the 4.3's espically the 94 and older s series. They are fairly easy to work on with most things.

 

Im talking about the pulley under the alternator. How do you do that one and what is it called

 

All you do is take out the bolt in the middle of it and it will pull right out of there. It shows you towards the end of the video.

 

Thank you so much

 

sometimes the bolts have left hand threads i cant rember if that one does or not
