There is no adjustment. It has a tensoner that keeps the belt tight.
Should have a spring loaded belt tensioner
No you can not. If belt is loose, are won't fit then you have the wrong belt. The belt tensioner is spring loaded and that is what tightens the belt.
There is no adjustment on the spring / Tensioner. You either have the wrong belt are the tensioner itself is bad. Replace tensioner are belt.
how to adjust headlights on 1992 silverado

Should automatically supply the proper tension for the serpentine belt - if not could be defective and require replacement
A 4L60E would not fit on a 91 Silverado because of the different dimensions.
no its the same belt that runs everything the tensioner may be getting bad or the belt routing might be wrong
how do you adjust rear brakes on a 1986 chevy silverado?
there is no adjustment for tension on a serpentine belt because there is a spring tensioner the belt goes around and if it is sticking and not keeping the belt tight enough you will have to replace the tensioner. They probably cost more than the labor to do it.
First you need a back window. Second You Need a 1999 Silverado. Third you will need tools to adjust it.
There is a belt tensioner that is spring loaded and it adjusts the tightness of the serp belt. The tensioner is self adjusting as the serp belt stretches out from use. You cannot adjust the belt tension yourself. If your serp belt is showing signs of cracking on the underside then you should replace it. If you suspect the belt tensioner is not putting enough tension on your serp belt then it should be replaced. I had a 1991 Corsica with the same motor and I had a belt tensioner break. This caused my serp belt to come off.
