Belt Tensioner

Keep Your Vehicle's Belts Tense and Your Shopping Relaxed
Don't mess around with a faulty belt tensioner! Get back in gear fast with help from your friendly neighborhood AutoZone. We carry a huge inventory of the best belt tensioners for cars and trucks, made for every essential system in your vehicle. Even better, they're also priced just right for your wallet.

Don't Let Critical Systems Fail
A failing belt tensioner can cause a lot of problems in your vehicle. The squeaking, squealing and grinding noises can certainly get on your nerves, but the potential problems caused by a bad tensioner are far more than just casual annoyances. If your instincts or curiosity made you pop open the hood and take a look at the belt, you probably noticed unusual or accelerated wear patterns. Frayed edges are the most recognizable sign, but that's before the belt breaks completely. And what happens then? The system or component relying on that belt fails. It could be your water pump, air conditioning, alternator or something else. That spells danger. An overheating engine or non-functional electrical system leaves your vehicle dead in the water. As for a broken AC system, try driving your car or truck in 100-degree heat. Not fun, right? Not to mention dangerous, especially when you consider that cabin temperatures can reach a scorching 30 to 40 degrees higher in just one hour parked in the sun.
