What is a tension pulley?

A tension pulley, also known as an idler pulley, is a crucial component in the engine system of a vehicle. It is responsible for maintaining tension on the serpentine belt, which drives various engine accessories such as the alternator, power steering pump, and air conditioning compressor. The tension pulley ensures that the belt remains properly aligned and does not slip, allowing the engine to function smoothly.

What happens when a tension pulley goes bad?

When a tension pulley goes bad, it can lead to various problems in the engine system. Here are some common issues that may occur:

  1. Increased friction and wear on the serpentine belt, causing it to deteriorate faster.
  2. Noise and squealing coming from the engine area due to belt slippage.
  3. Loss of power steering assistance, making it difficult to steer the vehicle.
  4. Diminished charging of the battery by the alternator, leading to potential electrical problems.
  5. Overheating of the engine due to the malfunctioning of the water pump.
