Engine Pulleys from Sears Keep your Vehicle Running

Idler and tensioner pulleys are part of a system of engine pulleys. In a belt and pulley system, pulleys do not use or generate power. They help to drive the system or power a part of your car but are not the source of the power or the part that uses it. They simply convert movement to a part of the vehicle that needs it.

An idler pulley, for example, guides belts and chains within an engine. It is made to press or rest a belt in order to give it the proper tension or to guide it. It tensions belts to keep them on track and running effectively. The idler pulley assists in regulating how the belts run from the crankshaft to generate movement in other parts of the engine.

The tensioner pulley is another type of engine pulley. It keeps belts from slipping. Pulley systems generally have a number of pulleys and belts wound around the pulleys. For the belt to properly fit around the pulley, there needs to be something to adjust the fit of the belt to the pulley. The tensioner pulley can provide this adjustment.

A vehicle owner can identify a worn or broken engine pulley by paying attention to key symptoms. The tensioner pulley may be nearing failure if you hear grinding, growling or squeaking. If, when looking at the car's engine, you can see the drive belt will not stay in place, the drive belt tensioner may need to be replaced. When replacing the drive belt or tensioner, it is a good idea to look at the system as a whole and consider replacing the idler pulley as well. In some cases, however, parts of the engine pulley system can be replaced separately. For example, the tensioner pulley can be replaced without replacing the tensioner.

Other parts of engine pulley systems experience wear with vehicle use as well. If parts of an engine pulley system are worn or broken, a vehicle will not run properly. The average user can identify a compromised engine pulley system. Vehicle owners can identify the condition of a pulley system by looking under the hood of the car. If a pulley system has failed, a belt may have snapped off or it may look impaired. Most car manufacturers give direction about the engine pulleys of each individual vehicle in the driver's manual. This will help the vehicle owner identify what parts need to be replaced and which brands or models are best for each automobile.
