Tensioner Auto.
Assembled device that applies load to the drive belt.
- 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 INFINITI's performance and handling, as it links the A/C, power steering, and alternator to the engine to make sure power continues to flow from the engine to these vehicle accessories.
An INFINITI old accessory drive belt tensioner may lead to 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. The INFINITI engine might start overheating. Or, you may experience a loss of charge from the alternator or a loss of power steering. These circumstances can make it very difficult, if not impossible, to keep driving!
It's a good idea to get a new Accessory Drive Belt Tensioner before you note severe wear and tear. Many INFINITI technicians recommend a replacement tensioner pulley around every 50,000-100,000 miles.
Replacing a car accessory belt tensioner at home requires advanced technical skills, since the process involves some unique tools, disconnecting the battery, picking the correct belt to replace, and adjusting the Accessory Drive Belt Tensioner to have the perfect amount of tension. 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.
