Have you ever started your car and heard a high-pitched noise originating from your engine? If yes, then there may be a problem with the belt tensioner. The tensioner is an important component of your vehicle’s engine, and as it wears out, it affects different parts of your vehicle. But how can you tell when the time has come for a replacement? Before we find the signs of a failing tensioner, let’s have a brief insight into what a belt tensioner does.

What Role Does a Belt Tensioner Play?

The belt tensioner is a small part of your engine but it plays an important role. Its job includes controlling the force level exerted on the serpentine belt driving the alternator, water pump, AC, and other components. The tensioner helps to appropriately tension the serpentine belt and other engine components when the engine is on. In the absence of a belt tensioner, the serpentine belt may loosen, slip, or even come off completely and this will lead to all sorts of engine problems.

Signs That You Need a Belt Tensioner Replacement

  • Squealing or Chirping Sounds: If, when you start the engine and it’s running, you hear either a squeal or a chirp, it could mean there’s a loose serpentine belt. Since the belt tensioner isn’t keeping the right tension, the belt will slip and produce that bothersome noise.
  • Visible Wear and Tear: You can also use visual inspection to know the condition of your belt tensioner. When you see cracks or wear on the belt or tensioner, it is probably time to get a replacement. If the tensioner pulley looks misaligned or moves a lot when the engine is in operation, this is a warning sign for the replacement of the tensioner.
  • Accessory Performance Issues: The serpentine belt’s ability to power other components is halted by a failed belt tensioner. You may find out that your car’s alternator is no longer charging the battery, or your AC unit has stopped working. If the power steering feels harder to control or any of your car accessories all of a sudden stop working, a broken belt tensioner may be to blame.

What Causes the Failure of a Belt Tensioner?

Like so many parts of your car, belt tensioners deteriorate due to regular wear and tear. The constant tension on the serpentine belt adds pressure to the tensioner, resulting in worn-out internal parts. Exposure to heat is also likely to promote quicker wear. Another reason for the failure of the tensioner is improper installation. If a previous replacement or repair of the belt tensioner was not done correctly, it may wear out faster or not operate as it should.

Replacing a Belt Tensioner

  • Inspection: The mechanic will first assess the belt tensioner as well as the serpentine belt to establish that the problem is with the tensioner.
  • Remove Serpentine Belt: To access the belt tensioner, the serpentine belt has to be taken off. This step should be done carefully because the belt revolves around so many pulleys in the engine.
  • Install New Tensioner: Once the old tensioner is taken down, the new one is placed and the mechanic will make sure that it is placed in the correct position.
  • Reinstall Serpentine Belt: When the tensioner is installed, the serpentine belt is replaced; the mechanic ensures that tension is optimal.
  • Test Drive: A test drive will ensure that the belt tensioner as well as the serpentine belt functions as required.
