Drive Belt Tensioner Replacement Service

What is the Drive Belt Tensioner all about?

A Drive Belt Tensioner is a pulley mounted to either a spring mechanism or to an adjustable pivot point that is used to keep constant tension on your serpentine belt. That is the big long belt in the front of your engine.

The tensioner rides on the outside surface of the belt to put pressure, or tension, on the belt and against the pulleys that drive things like the alternator, power steering, air conditioner, etc.

Keep in mind:

Tensioners usually come with pulleys; they are normally replaced together. Also, when replacing a tensioner, the drive belt usually must be removed. A mechanic may recommend replacing the belt as well.

How it's done:

  • Check for any noise in the engine (usually a squeaky or grinding noise).
  • Remove the drive belt(s) (in most cases).
  • Inspect drive belt pulleys.
  • Check the drive belt tensioner.
  • Remove and replace the tensioner if faulty.
  • Start car to see if noise is gone.

Our recommendation:

Your drive belt tensioner should always be inspected when your drive belt is serviced. During routine maintenance and inspection, your drive belt system should be reviewed to make sure that all the components are in working order. The drive belt tensioner will usually last longer than the drive belts, so as long as your tensioner is inspected or replaced when your drive belts are, your belt system should remain in good shape.

What common symptoms indicate you may need to replace the Drive Belt Tensioner?

Unusual noise (squeaky or grinding sound) every time you start the engine.

How important is this service?

The air conditioning, power steering, and alternator in your vehicle are given power through the drive belt. The belt is attached to both the crankshaft and these systems, and transfers power from the engine to drive each of these components. The drive belt tensioner is responsible for keeping the tension in the drive belt, which allows it to continue moving and transferring power. When the drive belt tensioner fails, the tension in the drive belt will begin to diminish, and the vehicle will not operate as well.

BMW 323i - Drive Belt Tensioner - Arlington, Texas
Fantastic Service! Rusty was very professional and friendly. He is very knowledgeable about car repairs in general, and specifically my vehicle. He arrived early and came prepared with the right tools and knowledge to take on the job. As it turned out the repair needed less parts that I purchased, and I will be returning what was not needed and saving even more money. Rusty also completed a thorough inspection of my vehicle, inside and out(he is great with paying attention to the details) and let me know of any trouble areas, along providing quotes for services I intend to schedule in the near future. I could not be happier!

Jason was great. He showed up early and fixed the issue requested no problem. He was professional and listened to what the issues were. He acknowledged that he would do some research about other issues I have on the car.
