Pulleys for your Auto from Sears Keep you Moving

Tensioner and idler pulleys are examples of common automotive pulleys. These affect how belts transfer motion from the crankshaft to various car parts. Engine pulleys do not create power but they use it to act on different car parts. They can, for example, be a critical component in activating a vehicle's alternator.

An idler pulley is a common automotive pulley in a vehicle. It guides belts and chains within an engine and is made to press or guide a belt in order to give it the proper tension or placement. In many vehicles, the idler pulley is used to provide tension to the serpentine belt. The serpentine drive belt system has one large belt that powers many different parts of a car. If this belt is loose or falls off the pulleys, it will affect performance of various parts of the car. A loosened belt is often a sign that the pulley has failed. Luckily, an idler pulley is easily changed.

To change an idler pulley, a vehicle owner first needs to remove the negative cable from the battery, and then loosen the tension adjustment bolt. Slide the belt off of the idler pulley. Hold the idler pulley so it cannot turn. Remove the bolt and pull the idler pulley off of the engine. Replace the worn idler pulley with the new part. Then repeat these steps in reverse order to finish installing your idler pulley.

The tensioner pulley is another common automotive pulley. This part keeps belts from slipping. Tensioner pulleys are often used in vehicles to apply the right amount of tension to the serpentine belt. Before replacing this part, consult manufacturer guidelines for specific instructions for your vehicle. Basic instructions for changing a tensioner pulley begin with finding the automatic belt tensioner and releasing the tension on the belt then removing it from the pulley. Let the tensioner spring return to its seated position and remove the tool. If you are replacing the belt, remove it from the pulley system. If not, let it stay intact with the rest of the system. Remove the automatic belt tensioner retaining bolt and the belt tensioner; install the new automatic belt tensioner. Replace the parts in the opposite order from which they were removed. Tighten to your vehicle's torque specifications. Release the tension on the automatic belt tensioner to move the belt back onto the pulley. Ensure the belt is properly snaked around the pulley system.
