What is an idler pulley?

An idler pulley is a specific part of a vehicle’s belt system that helps regulate how the belts run from the crankshaft to generate movement in other parts and engine accessories. It is one of a set of pulleys that a belt rests on. These engine belts are often called "serpentine belts" when they run across various pulleys, and they often run the air conditioning compressor, power steering pump, and alternator of a vehicle. Manufacturers generally provide a belt diagram that includes pulleys, either on a sticker under the hood or in the driver’s manual.

In many cases, the idler pulley is the point that is adjusted to replace a belt, and pulley replacement often includes replacing one or more belts. Mechanics talk about tensioners, which help provide the right level of tension on the belts. Vehicle owners can often adjust the pulley with a screw to gain or lose tension, and they can also move the idler pulley to release tension so that the belt can slip over it. They can then turn the tensioner to keep the belt tight and ensure its correct operation.
