What does a idler pulley do?
1. Support the drive belt
The idler pulley is responsible for helping support the drive belt and keeping it in place.
2. Maintain tension
It helps maintain the tension in the drive belt to ensure proper operation of the engine components.
3. Reduce vibrations
By providing a smooth surface for the drive belt to run on, the idler pulley helps reduce vibrations in the engine.
4. Prevent slippage
It helps prevent slippage of the drive belt, ensuring that power is efficiently transferred to the engine components.
5. Extend belt life
By reducing wear and tear on the drive belt, the idler pulley helps extend the life of the belt and other engine components.
What happens when an idler pulley goes bad?
1. Squeaking or squealing noises
When an idler pulley goes bad, it may produce squeaking or squealing noises due to friction.
2. Belt slipping
A bad idler pulley can cause the drive belt to slip, leading to decreased performance and potential damage to the engine.
3. Excessive wear on the belt
Due to misalignment or improper tension, a bad idler pulley can cause excessive wear on the drive belt.
4. Engine overheating
If the idler pulley fails completely, it can lead to engine overheating as the drive belt may not function properly.
5. Engine stalling
In severe cases, a bad idler pulley can cause the engine to stall, resulting in a breakdown and potentially costly repairs.
Does idler pulley need to be replaced?
