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.

Mercedes-Benz CLK500 V8-5.0L - Radiator - Yorba Linda, California
James did a great job replacing my radiator. He called to see if he could come a little early which worked out great. He was very professional, cleaned everything up after he was all done. Asked if I had any question about anything on my car and gave me a few pointers about an issue I was having with my hood shocks. I will for sure be calling him again when I need any service done to my car. I have already recommended him to 3 of my friends looking to get some work done on their cars.

Mercedes-Benz CLK500 V8-5.0L - Oil Change - Pleasanton, California
Trung called and arrived a bit earlier which I told him he could do that since I'm already back in my location. He took care of it like a pro and fast. I found out he has to drive from quite a distance away to my location which make me feel bad. My Mercedes warning light was all reset after the oil change and everything is back to normal. Found a minor leak in trans axle. Awesome job Trung. Keep up the good work.
