how to release serpentine belt tensioner on 1991 C1500 Chevy Silverado?
By loosening the tension on the alternator nut
Near the top of the serpentine belt path is a belt tensioner; it is spring loaded and has a shinney pulley on it. Insert a wrench into this tensioner and pull against it and the tension will be released so you can replace your belt. I am assuming your question is about the serpentine belt.
with a 9/16 socket and ratchet
Most likely there is a spring loaded device called a belt tensioner. There is a pulley on it with a bolt or square inset in it. sometime a socket or 3/8" drive extention can be used to move the pulley and release the tension on the belt.
It provides the proper tension on the serpentine belt so as it is not too tight or too loose.
What did unhook or break while you were under the hood ?
you do not adjust tension on a serpentine belt the tension is automatcally adjusted if the belt is loose, replace the belt SOME TIMES THE TENSIONER CAN BE WEEK ALSO.
