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.

Mercury Mountaineer V8-5.0L - Drive Belt Tensioner - Atlanta, Georgia
Was was very disappointed in Eric, Although he did a good job at replacing my Serpentine belt and the pulley, but he unexpectedly didn't replace the drive tensioner, which was the enitenial problem. Instead he keep the part. After he finished the work, he only left the old Serpentine drive Belt he replaced. And took all the other parts with him. I supplied my own parts, the the drive Tensioner came with the pulley already attached, so if he replaced all my parts like he said, then why did he find it necessary to take my old drive Tensioner and old pulley with him. I never laid eyes on it; to even see how badly it was damaged. You can clearly see on the engine that the tensioner was never replaced, only the pulley and the belt. I reported this with yourmechanic.com and I'm waiting for them to get back with me, once they finish looking into it.
