- The primary distinction between tensioners and idler pulleys is the presence of an adjustable bolt.
- Tensioners are positioned on the bolt through mounting.
- Idler pulleys are not mounted to an adjustable bolt.
- However, the differences between idler pulleys and tensioners also extend to purpose.
Thus, When should you replace idler pulley? An idler pulley is expected to wear over time, and eventually the pulley will fail. Replacement intervals for idler pulleys vary, but are usually within the 50,000 to 100,000 mile range. Replacement often coincides with expected serpentine/accessory belt replacement periods.
Additionally What happens if idler pulley fails? A broken or seized pulley can quickly lead to a torn belt, or in less serious cases, the belt falling off of the engine. An engine without a belt can quickly run into issues such as overheating and stalling, as it’s the drive belt that allows the engine accessories to function.

Can a bad idler pulley cause vibration?
Grinding noises – Grinding and rumbling noises are another common sign of tensioner or idler pulley failure, usually due to failing bearings. Excessive tensioner movement – Worn-out coil springs can also cause drive belt tensioners to loosen their grip on the drive belt, resulting in excessive vibration and rattling.
