Understanding the Idler Pulley Tensioner

The idler pulley tensioner is designed to add tension to the idle pulley and keep the idler belt and bearings from wearing out quickly. There are a number of different components inside the car that are powered through belts and pulleys, with the power being provided by the engine. The idler pulley is one of them, and it plays an important role in keeping your car’s systems running when it’s idle.

What Is it?

Perhaps the best definition of an idler pulley tensioner is a component that drives forces in a linear or a rotational motion system. It is a singular pulley that contains a myriad of different components and is designed to power multiple components of your vehicle. It consists of a sheave, which is an internal component that extends throughout the length of the roller. The idler pulley tensioner plays a key role in making sure that power delivery throughout multiple components of your vehicle remains efficient.

Wear and Tear

Like any other internal component installed within your car, the idler pulley is also going to wear out over time. When that happens, it’s going to reduce the performance of the pulley and power delivery will become inconsistent. You might start noticing a noise emanating from the pulley as well. In such cases, you need to take action quickly and get it fixed as quickly as possible. Don’t wait until the last minute till your car breaks down to get it repaired!
