• 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

The Accessory Drive Belt Tensioner helps balance and maintain the tension in the drive belt (serpentine belt). The INFINITI drive belt is important to your vehicle's overall handling and performance, as it connects the alternator, power steering, and A/C to the engine to make sure power continues to flow from the engine to these vehicle accessories.

A worn-out or broken INFINITI accessory drive belt tensioner might lead to a squealing noise when the engine is first started, or the drive belt will look frayed. If severely damaged, the Accessory Drive Belt Tensioner could cause the drive belt to break and then all of the accessories it powers to break along with it. The INFINITI engine might start overheating. Or, your vehicle could lose power steering or alternator charge. 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 INFINITI technicians recommend installing a new tensioner pulley around every 50,000-100,000 miles.

Installing a replacement INFINITI accessory belt tensioner requires more advanced automotive skills, since the process involves special tools, disconnecting the battery, picking the correct belt to replace, and balancing the Accessory Drive Belt Tensioner to have just the right amount of tension. If the belt isn't tight enough, it could get tangled up in other engine parts or fall off completely. If it is too tight, it will put stress on the system and cause other parts to stop working.
