Why should I replace the belt tensioner when replacing the serpentine belt?

It's common practice to replace the tensioner assembly when you replace the serpentine belt because a worn tensioner can cause premature belt wear or failure. Replacing them together saves you labor in the long run if the tensioner fails shortly after the belt.

What does a belt tensioner assembly do?

The tensioner assembly applies constant pressure to the serpentine belt, keeping it tight. This ensures that the belt can effectively drive accessories like the alternator, power steering pump, and air conditioning compressor.

Does this tensioner assembly come with a new serpentine belt?

This part is for the tensioner assembly only. The serpentine belt is sold separately, so you will need to purchase that in addition to this tensioner if you are replacing both.
