- Maintains the tension in the drive belt, which sends power to essential vehicle components like your alternator and power steering

Your Accessory Drive Belt Tensioner works to hold the tension in the serpentine belt, also called the drive belt. The drive belt is imperative to your Nissan's performance and handling, as it links the alternator, power steering, and A/C to the engine to ensure power flows from the engine to all of these accessories.
A worn-out or broken Nissan accessory drive belt tensioner could cause a squealing noise when the engine is first started, or the drive belt will look frayed. If extremely worn out, the Accessory Drive Belt Tensioner can cause the drive belt to snap and all of the accessories it powers to fail along with it. Your Nissan engine can overheat. Or, your vehicle could lose power steering or alternator charge. These situations can make it nearly impossible to keep operating your vehicle.
It's best to replace the Accessory Drive Belt Tensioner before you notice extreme wear and tear. Many auto technicians suggest replacing the tensioner pulley at 50,000 to 100,000 mile intervals.
Installing a new Nissan accessory belt tensioner on your own requires experience and automotive knowledge, since the process involves a handful of special tools, disconnecting the battery, identifying the correct belt, and adjusting the Accessory Drive Belt Tensioner to have the exact amount of tension necessary. If the belt is too loose, it could fall off and get pulled into other engine parts. If it is too tight, it will put extra strain on the system and cause components to seize up.
