This Michelin Serpentine is amazing! I changed my alternator so thought it would be a good idea to change the serpentine belt as well. My old V-belt was neither broken nor in need of visual repair. But I've changed anyway. I think the Michelin belt quality is much better than the old one because my car seems stronger! Now I only buy Michelin. Btw, my old one was a Dayco that worked, never squeaked and looked new after 5 years. I will keep it in case my Michelin fails.
