How Long will Car Serpentine Belt Last?


Thanks to improvements in rubber technology, the car serpentine belt lasts longer than it did before. Most serpentine belts typically last from 50,000 to 100,000 miles. Eventually, your car's serpentine belt will wear out from constant exposure to heat and friction and will need to be replaced.


What are the Signs of Failure of Car Serpentine Belt?


As a car serpentine belt ages and wears down, rubber parts may peel off, causing the belt to break, fray, or slip. When these things happen, it may become misaligned or fluid contaminated. There are a variety of signs that may indicate that your car's serpentine belt is wearing down, including:


  • The sound of squeak or chirp: As the serpentine belt begins to slide, it may start to squeak or chirp. The sound indicates that there is belt stretching, belt tension is low, or the pulley and belt are not working properly. 


  • Cracks and wear: You may notice physical signs of failure, including missing chunks, cracks, damaged ribs, uneven wear, or rib separation. 


  • Air conditioning or power steering failure: If the serpentine belt fails or breaks, you may notice that your air conditioning is not working well. In addition, your car's power steering system, alternator, or water pump may fail, leading to serious safety problems.


  • Car breaking down: When the serpentine belt completely breaks, your vehicle will stall, which can be extremely dangerous and inconvenient. 


When there is a problem with your belt, your check engine lights and other gauges will warn you. Don't ignore warning signs of serpentine belt failure.


Advantage of Car Serpentine Belt Replacement


If you drive with a worn-out belt, you are running the risk of engine accessory failure. When the belt slips or breaks, your car's functions, such as the alternator and power steering pump, may stop working. A damaged belt may also damage the components it drives. It's bad enough to deal with a broken belt or hose, but it's even worse if your engine breaks. By regularly replacing your serpentine belt, you can reduce the risk of a car breaking down. It lets you enjoy your car and drive carefree.


Most serpentine belts on modern vehicles have tensioners. Serpentine belts perform best only with the correct tension. The belt tensioner applies perfect tension to keep the serpentine belt running with proper resistance and speed for optimal function. When you replace your serpentine belt, you should also check your belt tensioner and pulley.


Although most cars today only have a serpentine belt to control various systems, some vehicles use other types of rubber belts. For example, older ride cars use a serpentine belt with a series of automotive v belts. Some cars are also equipped with a car timing belt to drive water and oil pumps to important parts like the engine.
