Seat belt tensioners represent an integral facet of contemporary automotive safety systems. These sophisticated devices are meticulously engineered to augment passenger protection by mitigating the potentially injurious effects of a vehicular collision or abrupt deceleration event.
Belt tensioner noise is typically an indication of a problem within the engine's accessory drive system, and it should not be ignored.
Squealing or Whining Noise: A common sign of a failing or worn-out belt tensioner is a high-pitched squealing or whining noise. This noise is often most noticeable when you start the engine or when you engage accessories like the air conditioner or power steering.
Rattling or Grinding Noise: A failing tensioner may also produce a rattling or grinding noise, especially at higher engine speeds or when the drive belt is under load.
Intermittent Noise: The noise produced by a failing belt tensioner can be intermittent, depending on factors like engine temperature and load.
Replacing a belt tensioner is a relatively straightforward mechanical procedure, but it does require some mechanical knowledge and the right tools. Steps to follow when you are planning to replace your seal belt tensioner.
