I recently replaced my old car belt with the ACDelco Professional V Ribbed Serpentine and I must say, I am impressed with the performance .Based on my experience, this is an excellent product for any automotive enthusiast. It fits perfectly with my cars engine and runs smoothly even during long drives. Moreover, it is very durable and has a longer lifespan than any other belts I have used before. The only downside is that it’s slightly more expensive than SOME of its competitors in the market..
