Serpentine Belt

What does a serpentine belt do?

The rubber belt that loops around rotating engine parts is called a serpentine belt. It typically has numerous V-shaped grooves that run vertically along the belt's length and is made of high-quality reinforced rubber.

Important engine accessories like the alternator, power steering pump, air conditioning compressor, and (occasionally) water pump receive mechanical power from the serpentine belt.

It is sometimes referred to as the following because of what it powers:

  • Accessory drive belt
  • Fan belt
  • Accessory belt
  • Alternator belt

What should I look out for or inspect in a serpentine belt?

The serpentine belt is prone to deterioration, fraying, cracking, shininess or "glazing," and rubber components may come off the belt. In addition to slipping or squealing, fluid contamination, or misalignment, an old belt can also start to act up, necessitating replacement. A worn-out belt also has the potential to snap, losing all drive torque to the engine's accessories.

Some automobiles also use drive belts to power the coolant pumps. If the belt snaps, the engine won't receive the proper amount of coolant to keep it cool. The engine will overheat, possibly resulting in serious harm.

What is the average lifespan of a serpentine belt?

A serpentine belt should have a typical lifespan of 60,000 to 100,000 miles under ideal circumstances. However, some belts are required to be adjusted more often because they are manually tensioned. Others have a self-tensioning system that may require maintenance due to wear over time.

Keep in mind that the vehicle will typically stop running if the serpentine belt ruptures. Therefore, make sure your serpentine belt gets a checkup if symptoms appear or if you've reached the 50,000-mile mark.
