Review on Continental Elite Poly-V/Serpentine Stretch Belt: Superior Performance and Durability by Steven Harper

Belt grooves were poorly defined Belt was installed and centered on all pulleys/grooves as I have done on every car I have had in the last 30 years. However, on the first start it jumped off the alternator pulley and broke through the middle. Went to the local auto parts store and got a replacement from a different brand and it worked fine.
