The ACDelco belt is hands down the best serpentine belt I`ve ever used on my car... As a result of my tests, I determined that it is extremely durable and can WITHSTAND high temperatures without cracking or squeaking. The ribbed design also ensures that the belt lasts longer and provides better grip, resulting in a smooth and quiet ride. The only downside is that it may be slightly more expensive than other options on the market but it is well worth the investment for its quality..
