The primary job of the serpentine belt is to provide vital traction to spin the accessories. As the belt wears it loses some of its grip and the accessories may not spin at prime speeds. For example, if your alternator doesn’t spin fast enough, the battery will not completely recharge while you’re driving and you could end up stranded with a dead battery.

In short, a worn serpentine belt will stress all of the accessories it powers leading to premature wear and possible early replacement. When as little as 5% of belt material is lost, the serpentine belt cannot provide the proper traction for the accessories. Your honest Parkway Automotive service specialist can inspect your belt for excessive wear and replace your serpentine belt system if it’s excessively worn.

Your serpentine belt drives important engine accessories like your alternator, air conditioning compressor, and power steering. In some automobiles it may also power the power brakes or water pump. The serpentine belt is powered by the engine and winds around pulleys and the accessories. Some vehicles have two serpentine belts.

The serpentine belt, the belt tensioner (which maintains the appropriate tension on the belt) and the idler pulleys are together known as the accessory drive system.

Now your serpentine belt and the belt tensioner will just wear out over time – that’s why your auto manufacturer has a scheduled belt replacement interval. The team at Parkway Automotive in Little Rock can review your serpentine belt for wear and get it replaced if it’s time.

The serpentine belt tensioner applies pressure to the serpentine belt, maintaining prime tension to drive the accessories like the alternator and A/C compressor. The service life of the belt tensioner is the same as the belt itself, so they should always be replaced together. A worn tensioner impedes the accessories from spinning properly, leading to premature wear and noise.

Your auto maker has a recommended mileage interval for serpentine belt replacement. A complete accessory drive system service replaces the serpentine belt, the belt tensioner and any idler pulleys your vehicle might have. Your honest Parkway Automotive service specialist can review your system and let you know if it’s time for a replacement.
