What is a tension pulley?

A tension pulley, also known as an idler pulley, is a component of the engine's accessory belt system. It is responsible for maintaining tension in the belt, ensuring proper operation of various engine accessories such as the alternator, power steering pump, and air conditioning compressor.

What happens when a tension pulley goes bad?

When a tension pulley goes bad, it can lead to several issues with the engine's performance and functionality. Here are some common problems associated with a faulty tension pulley:

  1. Unusual noise: A worn-out tension pulley may produce squeaking or grinding noises.
  2. Decreased belt tension: A failing tension pulley may fail to maintain proper tension in the belt, causing it to slip or come off completely.
  3. Accessory failure: If the belt slips or comes off, it can result in the failure of engine accessories such as the alternator or power steering pump.
  4. Overheating: In some cases, a loose or damaged tension pulley can cause the engine to overheat due to the malfunctioning of the water pump.
  5. Increased wear: A malfunctioning tension pulley can cause increased wear on the belt and other associated components, leading to further damage.
