A well-maintained serpentine belt powers crucial automotive components. It is one long, winding belt that keeps your alternator, power steering pump, air conditioning (and in some vehicles, your water pump) running smoothly and effectively. It does this by transporting power to your vital automotive components. Some vehicles may have an additional belt to run select accessories, but the serpentine does the bulk of the work.
How Long Does a Serpentine Belt Last?
Your vehicle’s serpentine belt can now last between 60,000 and 100,000 miles. Eventually, your serpentine belt will wear down from continuous exposure to heat and friction and will need to be replaced. In most cases, if the Serpentine Belt breaks, the vehicle will stop running.
