Belt Tensioner Assembly

What are Belt Tensioner Assemblies and what do they do?

Your serpentine belt controls several different parts of your entire vehicles power components. The belt tensioner assembly makes this possible, in part, by maintaining the proper levels of tension on the belts. The serpentine belt is a long, winding belt that helps to keep your alternator, power steering pump, a/c and — in some cases — your water pump running without problems efficiently.

When should I replace my Belt Tensioner Assembly?

There will be a recommended mileage at which this part should be replaced specified by your auto’s manufacturer. Alternately, if you have problems related to this part, it can be replaced at any time.

What happens if I don’t?

The most common problem caused by worn belt tensioner assemblies is unevenly worn serpentine belts. Remember that these belts cost a lot more than regular engine belts, in many cases, so keeping them in good condition makes financial sense. Your vehicle may also be undriveable if your belt becomes too damaged because belt tensioners tend to maintain constant tension on the belt to extend both belt and accessory drive bearing life.

How to do it: Replacing Your Belt Tensioner Assembly:

Replacing the serpentine belt tensioner assembly is a relatively easy repair for anyone with basic automotive maintenance skills. Consult with your owner’s manual to find the locations of all the parts involved.
  1. Using a socket wrench, remove the bolt located in the center of the belt tensioner pulley. This will be found on the front of the engine. Be sure not to confuse it with the pulleys that control the crankshaft and the alternator.
  2. Loosen the serpentine belt by rotating the wrench clockwise—it is threaded backwards relative to most other bolts. The serpentine belt should slide right off once the tension is removed.
  3. Finish unbolting the tensioner.
  4. Remove the assembly.
  5. Replace the assembly with the new tensioner.
  6. Reattach the serpentine belt, reestablishing the proper tension to by tightening down the center bolt on the tensioner.
TIP: Check the tension on the serpentine belt before removing the tensioner so you can more accurately restore it after replacing the tensioner.
