Symptoms of a Bad or Failing Idler Pulley

- Belt squealing. Another common symptom of a possible issue with the idler pulley is squealing from the engine belts.
- Damaged bearing or pulley.
What happens when a pulley goes bad?
When the engine is idling, a bad pulley may make a squealing sound. This is due to the bearings in the pulley going bad. The bearings may also make various other sounds such as clattering or even a rumbling sound, making the vehicle sound as if there was much more wrong than a bad pulley.
How many pulleys are in a car?
Cars have 2 types of belt pulleys, the idler and the tensioner. Some cars have only one of each type, although there are those that may have more than one idler pulley.
