Ribs that crack or fray, or a squeal when the engine starts, can mean the belt is worn, though a weak tensioner or a misaligned idler can be behind them as well.
This serpentine belt also fits the 1998-2001 Nissan Altima and the 2000-2004 Toyota Tundra V6 3.4L, plus many other vehicles. If your car is not named here, find your year, make and engine in the "Vehicles it fits" section.
