Q: How to Remove and Install a Drive Belt with a Dynamic Tensioner on 2000 Dodge Viper?
A: The tension of the Poly-V (Serpentine) Drive belt is controlled by a dynamic tensioner. Before you remove the belt, remove the air cleaner ducts. After that, loosen the belt tension by turning the tensioner clockwise with a 15 mm wrench over the tensioner idler pulley bolt. Just go back through the steps you followed before to install the fan.
