Serpentine Belt
I replaced the largest Serpentine belt on my 1999 Conv Vette, no real problem, I believe I used a metric # 13 wrench to move the teniometer, but I really had a tight fit on the installation, I believe I took up the tension and slide the belt over the Alternator last. Also I believe there are two belts and two teniometers, be sure and check this out. The lower one runs the Air. Doc
