I am trying to tighten the alternator belts, as they are squealing very badly. Have to do it from below, as the turbo blocks it from above. I loosened the upper bolt that slides along a "channel", and the lower bolt a little, too. Just above the alternator there is something protruding on the the top outer side of the alternator (as I look up from below), hex-shaped, and about an inch or two long. I thought this would be the tensioner, but when I try to turn it with an open-end, it doesn't turn freely.... it twists a bit with lots of force, like I am going to snap it off. What am I dong wrong?
