- Maintains the tension in the drive belt, which sends power to essential vehicle components like your alternator and power steering
- If failing, it could cause the engine to overheat and loss of power steering system
- Generally needs to be replaced about every 50,000 to 100,000 miles
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 goes from the engine to these accessories.
An old, worn-out Nissan accessory drive belt tensioner might 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, you could end up with a loss of power steering or loss of charge from the alternator. These events can make it nearly impossible to keep operating your vehicle.
It's a smart move to install a replacement Accessory Drive Belt Tensioner before you note severe wear and tear. Many Nissan technicians recommend a replacement tensioner pulley about every 50,000 to 100,000 miles.
Installing a replacement Nissan accessory belt tensioner requires experience and automotive knowledge, as the process involves a handful of special tools, uncoupling the car battery, selecting the right belt, and adjusting the Accessory Drive Belt Tensioner to have the exact amount of tension necessary. If the belt is too loose, it could get tangled up in other engine parts or fall off completely. If it is too tight, it can strain the system and cause other parts to seize and stop working.
