What happens if your belt breaks while driving?
If a serpentine belt is broken, it can lead to a sudden loss of power assist for the steering system. This happens because the serpentine belt keeps the water pump circulating coolant, also known as antifreeze, through the cooling system. This means that the engine can overheat anywhere, including the highway.
How do you diagnose a squeaky belt?
One method to determine if the noise is a chirp or squeal is to use a water squirt bottle and spray the rib side of the belt while the vehicle is running. If the noise gets louder, it’s a squeal. If the noise goes away, it’s a chirp.

Can you replace just the pulley on a tensioner?
The tensioner pulley is on the end of a spring-loaded tensioner. More often than not, just the pulley goes bad on the tensioner, not the whole tensioner, and for most vehicles, you can purchase and replace the pulley instead of the tensioner itself.
