• Transmits power through and to the alternator, power steering pump, and A/C compressor
• Also known as a fan or accessory belt
• Replace when cracked, frayed, peeling, or malfunctioning

Your Nissan's motor depends on various complicated, interconnected components that support the signature Nissan ride you know and love. Many of these Engine components connect via a series of belts, one of which is called the Serpentine Belt.

The Serpentine Belt is a sturdy, cyclical strap that conduct power through and to the power steering pump, alternators, A/C compressors, and, in some cases, to the water pump, too. Some refer to the Serpentine Belt as the accessory or fan belt because it powers your Nissan's peripheral devices. However, that simple reference doesn't make it any less important.

Serpentine Belts are generally made of tough-but-flexible rubber engineered to withstand the friction and heat involved in transporting power from one engine component to the other. But, like all good things, even Serpentine Belts don't last forever!

With age, Serpentine Belts can fray or crack or they can malfunction if they become soaked due to coolant or oil leaks. Also, they may lose tension, lack alignment, or slip because of malfunctioning tensioning systems, which may result in needing to replace both the tensioner and the Serpentine Belt, or recalibrating the belt, if possible. A few signs that you might have Serpentine Belt problems include: engine rattling noises, lackluster A/C or power steering performance, engine sweltering, and visible cracks or wear on the belt.

In general, your Nissan Serpentine Belt is one of your most long-lasting parts, but issues like oil leaks and worn tensioner mechanisms can significantly shorten its lifespan. You should inspect your Serpentine Belt any time you change the oil, or a Nissan expert can do it for you when you visit one of our service centers near you.

The Serpentine Belt replacement procedure is dependent on the tensioner mechanism in your Nissan. Consequently, it's best to check your Nissan's manual before replacing the Serpentine Belt yourself.

Without a doubt, it'll involve a Serpentine Belt with proper fitment for your Nissan model, and an adequate belt tensioner. If your Nissan has a hydraulic or manual tensioner mechanism, it may be a smarter choice to visit your nearest Nissan experts for professional assistance.

When you're ready to get started, take pictures of the placement of your current Serpentine Belt and of how it winds around the motor's different parts. Then, use a ratchet to release the tensioner and delicately unwind the Serpentine Belt, taking care not to mess with any accessories.

Once you've undone the old belt, check it for signs of engine oil or coolant leaks, cracks, and wear to identify any other issues that may not be resolved by just replacing the belt! Re-thread a new Serpentine Belt in the old one's place and release the tensioner, tightening it with a wrench. Lastly, turn the engine on and idle it while you observe the new belt's operation to ensure it is installed correctly.
