A tension pulley, also known as an idler pulley, is a component that keeps the drive belt under tension in an engine. Its purpose is to ensure that the belt remains properly aligned and doesn't slip off. By maintaining the right tension, the tension pulley contributes to the smooth operation of various engine accessories.

What happens when a tension pulley goes bad?

When a tension pulley goes bad, several issues may arise:

  1. Increased belt wear and tear: A faulty tension pulley can cause excessive friction, leading to accelerated belt deterioration.
  2. Belt slippage: Insufficient tension may cause the belt to slip off, resulting in loss of power to engine accessories such as the alternator or power steering.
  3. Noise and vibrations: A worn-out tension pulley may produce squealing or rattling noises and cause vibrations in the engine compartment.
  4. Overheating: Inadequate tension can cause the belt to overheat, potentially leading to engine overheating.
  5. Complete belt failure: If a tension pulley fails completely, the belt can dislodge, resulting in a complete loss of power to all engine accessories.

When to replace a tensioner pulley?

It is essential to replace a tensioner pulley under the following circumstances:

  • Excessive belt wear: If the belt shows signs of cracking, fraying, or other forms of damage, it is crucial to replace the tensioner pulley.
  • Noise and vibrations: Unusual noises or vibrations from the engine compartment may indicate a worn-out tension pulley.
  • Difficulty in belt tension adjustment: If the tensioner pulley no longer allows proper adjustment of the belt tension, replacement is necessary.
  • Visible damage: Physical damage to the tensioner pulley, such as cracks or missing parts, warrants immediate replacement.
