Alternator removal....

[z5050z]

I've got a 2001 4.8 Silverado, I need to replace my alternator. I see two bolts holding it in place, do I have to loosen the belt some how, or do I just remove those two bolts and it will come right out?

Belt tensioner is spring loaded on the upper right. You will have to take the belt off.
