Drive Belt Tensioner Replacement Service & Cost

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.

Joe has been my mechanic in the past. If there is a delay due to parts or a timing issue, he calls to give me an update on his job status and notifies me when he's on his way. He is very personable and polite and I trust him to do the job right and at the quoted price. I will definitely use Joe again!

Without a doubt Michael is the best mechanic in Charlotte!!! He showed up an Hour early for my appointment because he knew everything I was going through was last minute and wanted to get to me as soon as possible!! My car was stranded at a friend's house and was not there when he arrived but he basically completed my service by the time I had arrived (still 40 minutes before my scheduled time) and was nice enough to look at my friends car while he was waiting on my keys to finish up with my appointment!! My friend needed almost 3 bottles of transmission fluid because it was so empty and Michael happily filled his transmission with fluid he had on him...Free of charge!! And diagnosed my friends car with his recommendations for that as well. Honestly can not say how how I am Michael is my Only mechanic!! He is probably the nicest guy ever, comes Fully equipped with everything possibly needed for mechanics, is extremely informative, best person I have met at timeliness, and is 100% trustworthy!!! If you have the luxury or getting Michael consider yourself lucky!!! Great great great guy!!!!
