After countless research and browsing, I finally decided to give this serpentine a try for my automotive needs .Through trial and error I found that this particular product truly deserves recognition. The drive is now smoother and quieter with minimal vibration. The pulley's shape is great, offering durability for extended use. The only downside is the installation can be slightly difficult, requiring special equipment. Overall, highly recommend it for your hoses and pulleys needs in car belts..
