I was able to change my belt in about 30 minutes w/o loosening the tensioner. I wouldn't do this if the belt tension was questionable otherwise...
...I used a screwdriver to gently coax the belt to slide off one of the pulleys...easiest to do on one of the pulleys that engages the smooth side instead of the grooved side.
I will admit that I was in the process of replacing an alternator...I had removed the fan blades and fan shroud for easier access.
