Symptoms of a Bad or Failing Idler Pulley

Idler pulleys are engine pulleys that are responsible for guiding and tensioning the engine drive belts. The engine drive belts are routed in a specific manner around the various engine accessories, such as the alternator, water pump, power steering pump, and AC compressor. The idler pulley is meant to provide another smoothly rotating point for the engine belt to loop around, so that the desired routing can be achieved. Most engines use one idler pulley, and one tensioner pulley, though some designs do use more than one idler. Over time, idler pulleys will eventually wear out and need to be replaced. Usually a bad or failing idler pulley will produce a few symptoms that can notify the driver of an issue.
  • Visibly worn pulleys. One of the first symptoms of an issue with an idler pulley is visible wear on the pulley.
  • Belt squealing. Another common symptom of a possible issue with the idler pulley is squealing from the engine belts.
  • Making noise follow revving
