to clarify, the pulley by itself will not turn, it is turned by the motion of the belt
moveing on in.

What is the function of the idler pulley on cars?
Idler pulleys are used to maximize belt contact with other pulleys and to redirect belt around other parts that might interfere with the belt.
Are idler pulleys and fan hubs the same?
Idler pulleys and fan hubs are not the same; they serve different purposes in machinery. An idler pulley is used to guide and tension a belt in a drive system, often found in engines or conveyor systems. In contrast, a fan hub is a component that connects the fan blades to the motor, allowing the fan to rotate and provide airflow. While both are mechanical components, they have distinct functions in their respective systems.
Do idler pulleys spin?
Idler pulleys do not actively drive any components in a system; instead, they serve to guide or tension a belt. While they are not powered themselves, idler pulleys can spin freely as the belt moves over them. Their primary function is to maintain proper belt alignment and tension, ensuring smooth operation of the overall system.
How much are idler pulleys?
They very in price, depending on the car, from around $12 to $80.
How many idler pulleys are on a Ford Escort?

When to replace upper and lower idler pulleys?
only if the idler arm will not hold the tension on the belt and the pulley needs replaced when the are warn sharp or warn flat
What is the difference between deflection and idler pulley?
A deflection pulley is used to change the direction of a belt or chain, while an idler pulley is used to maintain tension in the belt or chain. In other words, deflection pulleys guide the belt around corners or obstacles, while idler pulleys help keep the belt taut and prevent slipping.
What are idler pulleys?
== == it is a free pulley that works as a tensioner on any belt bolted to hold or spring loaded An idler pulley usually tensions a belt.. eg supercharger belt is kept taut by its respective idler pulley
Does a car have a pulley?
The engine usually has an idler and/or tensioning pulley as well as a few pulleys that use the power of a traveling serpentine belt to drive components such as the alternator, a/c pump, etc. Any of the pulleys that have one or more grooves that assist to guide the belt(s) are, technically, sheaves. Idler or tensioner pulleys that are completely flat because the flat back of the belt rides on them are not sheaves, but are pulleys.
Why does the tensioner bolt keep breaking on my 2001 Ford Escort ZX?
An accessory or idler pulley is frozen or in very bad shape and is snapping the tensioner and bolt from all the torque being applied to it. Check all your pulleys when you have it off. They should rotate freely.
How do you put a serpentine belt on a 1991 Mercury Cougar?
Put an 18mm wrench on the lower tensioner belt and rotate CCW to loosen the tension. Remove the belt from around the alternator pulley, and slowly release the tensioner. Unwrap the belt from all the pulleys and install the new belt following the belt diagram located near the radiator support. ALWAYS make sure the grooved side of the belt is contacting the grooved pulleys, and the smooth side of the belt is contacting the smooth pulleys (Idler pulleys). Groove to Groove -- Smooth to Smooth
How do you replace timing belt on a 93 subaru legacy?
Take it to the dealer! It's not a job for the timid or any shop that doesn't know what they are doing. Make sure you get the idler pulleys and automatic tensioner replace along with the timing belt. If the bearings seize in those idler pulleys it will ruin the belt and in turn take out your engine.
