We at KLM Performance recommend you do a thorough visual inspection of the serpentine belt at every oil change.

We also recommend that you check the function of the Serpentine Belt Tensioner as this engine component is also considered a wear item that needs replacement. The serpentine belt is kept under constant tension by the belt tensioner. A worn serpentine belt tensioner is usually noticeable by the chirp heard when you shut the engine off. The Serpentine Belt is kept at the proper tension by the Belt Tensioner for good engine performance. With age, this component begins to wear just like the Serpentine Belt.
