This serpentine belt does not disappoint .As an automotive enthusiast I have used many belts and this is by far one of the best. As a result of using this product, I found that my car's engine is much quieter and runs smoother. The belt seems to be made of high-quality materials, which means it will last a long time. However, the only downside is that it's a bit pricier compared to other belts on the market. But for the durability and improved performance, i definitely recommend it..
