Default alternater replacement

I am posting but it is really my son's car. He won't do a sig pic until he gets his car painted.

My question....
Without a service manual yet I'm sure that the experience here can direct me to the serpentine belt tension adjustment procedures.

1991 coupe

Thanks in advance

unless it's different than my 85, there is no adjustment. You take the tension off to take off the belt and the oposite when reinstalling

Should have automatic belt tensioner/pully. push away from belt to unload tension.

Your son's 91 Corvette has a spring loaded belt tensioner on the right side of the engine and no adjustment is necessary. There is a 1/2 " square hole in the tensioner arm that you put a 1/2 " breaker bar in to unload the belt tension to remove the belt, and you do the same to install the new belt .

Worked like a charm!

These cars are pretty easy to work on.

Thanks to all
