What does a Serpentine Belt do?

The serpentine drive belt gets its name because it snakes around several components of your engine – including the alternator, air conditioner, power steering and water pump – and powers them as the crankshaft turns.

When should I have Serpentine Belt Replacement?  

The serpentine belt drives several engine components. So, when the belt fails, all the associated components – the alternator, air conditioner, power steering and water pump – stop working. That’s why it’s in your best interest to replace this belt before it breaks.  Dale’s quality trained technicians will visually inspect and measure your drive belt(s) before its too late.  We generally recommend that your serpentine belt is inspected for signs of wear when your oil is being changed.

Listen for signs of wear, too. A squealing belt may need to be replaced.  We recommend that you plan to replace the serpentine belt as preventative maintenance every 100,000-120,000kms.

Over 100 million vehicles use automatic belt tensioners. Tensioners are designed into the belt drive system for several reasons:

 

  • Proper tension is maintained throughout belt life.
  • Reduce maintenance by eliminating need to re-tension belts on a periodic basis.
  • Provides consistent and correct belt tension, thereby increasing bearing life of accessories.
  • Increase belt life because belt is not over or under tension.
  • Prevent belt slip. A belt that slips is not only noisy but can also cause accessories to not function properly.
