What is a serpentine belt?
The engine in your car has many roles to fill. It has to do more than move. It also has to generate electricity, assist with power steering, cool off the passengers, and keep itself cool. The serpentine belt - sometimes referred to as the fan belt, alternator belt, or accessory drive belt - is used to spin, or "drive," several components attached to the engine. It drives the alternator that powers the electrical system and recharges the battery. It also drives the power steering pump, the air conditioning compressor, and the water pump. (The water pump circulates coolant through the cooling system). In the past, multiple drive belts were used to turn pulleys attached to these components. Today, most vehicles employ just a single belt - the serpentine belt - to do the job.
How does the serpentine belt work?
As the engine's crankshaft pulley turns it drives the serpentine belt. In turn, the belt drives the pulleys for the other systems including the air conditioning, alternator, water pump, cooling fan, and power steering.
What are the symptoms related to a bad serpentine belt?
Over time serpentine belts stretch, crack, and the ribs that ride on the accessory pulleys being to wear smooth. A squealing noise that increases with engine speed or as engine driven accessories are turned on may be noted. The noise is caused by the belt slipping on the pulleys, insufficiently driving them. Ineffective air conditioning, a battery warning light, or intermittent power steering assist can result from this.

Can I drive with a serpentine belt problem?
A slipping belt means one or all of the accessories are not being driven properly. Loss of air conditioning, electrical power, power steering, or water pump and fan drive are possible depending on the severity of the wear. If left for too long the belt can shred or come off of the pulleys. The belt should be inspected as soon as is convenient to protect against becoming stranded.
How often do serpentine belts need to be replaced?
Replacement intervals vary by vehicle and driving conditions. We typically see this part replaced approximately every 100,000 miles.
