What is the serpentine belt configuration?
The serpentine belt wraps around several engine-driven accessories fitted with pulleys, as well as the engine’s crankshaft pulley. Whenever the vehicle is running, the engine’s crankshaft pulley turns the serpentine belt. The belt then drives the various accessories (i.e., alternator, air conditioning compressor, etc.)
How do you visually inspect a serpentine belt?
Here are tips for inspecting belts:

How long does a serpentine belt last?
60,000 to 100,000 miles
