Alternator 1989 Buick Century

I am replacing the alternator in my '89 Century, but I'm not sure how to take the tension off the belt. There is a small idler pulley below the steering fluid pump... can't tell if that's a tensioner or just a pulley? Any help or suggestions are appreciated.
thanks

put a wrench...

...on the bolt head in the center of the pulley and try to swing it one way or the other, if it doesn't move, it's just an idler...but there IS a tensioner on it. the tensioner may have a square hole in it for you to put a 3/8" ratchet drive (or a breaker bar) into. some even have a square end at the end of the tensioner assembly that you can put an open end wrench on....personally, i believe that yours will have the first type i mentioned and it has an 18mm bolt that you use to swing the tensioner with.
