There are 4 common causes of belt noise - the belt is worn, a bad bearing in the pulley, belt tension and pulley misalignment. Belts need to be replaced every 6 years or 60,000 miles and eventually the bearings go bad. There are several pulleys associated with the timing mechanism. Incorrect belt tension is due to a worn belt or a malfunctioning tensioner. These problems are easily fixable with premium replacement parts from AutoAnything.
