Your Nissan engine relies on a variety of intricate, interrelated parts that get you the powerful Nissan drive you cant live without. Many components connect through a network of belts, and one of the most important belts is the Serpentine Belt.
Your Nissans Serpentine Belt is a strong, continuous belt that transmits power through and to the A/C compressor, power steering pump, alternator, and, in some cases, water pump. Some people refer to the Serpentine Belt as a fan or accessory belt because it engages your Nissan engines peripheral devices. However, you shouldnt underestimate its importance.
Serpentine Belts are usually made of ultra-sturdy rubber thats specially designed to endure the heat and friction involved in transporting power from one engine component to the other. However, like any other part, they are subject to wear and tear.
Serpentine Belts can fray, crack, or even peel with age, or they can malfunction if they become soaked due to oil or coolant leaks. Additionally, they can slip, lose tension, or become misaligned because of malfunctioning tensioning systems, which may result in needing to replace both the tensioner and the Serpentine Belt, or re-adjusting the belt, depending on its condition. A few signs that you might have Serpentine Belt problems include: engine rattling noises, lackluster A/C or power steering performance, engine overheating, and visible cracks or wear on the belt.
Typically, your Nissan Serpentine Belt can last many thousands of miles, but its useful life can be shortened due to coolant leaks, oil leaks, and old tensioners. 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 required method for a Serpentine Belt replacement is dependent on the tensioner mechanism in your Nissan. Consult with an expert technician or your Nissan manual before DIY-ing any services!
In most cases, itll involve a Serpentine Belt with proper fitment for your Nissan model, and an adequate belt tensioner. Note that if your Nissan relies on a manual or hydraulic tensioner for the Serpentine Belt, it may be a smarter choice to visit your nearest Nissan experts for professional assistance.
When youre ready to get started, take pictures of the placement of your current Serpentine Belt and of how it intertwines with other engine components. Then, detach the tensioner using a ratchet and gently unravel the Serpentine Belt, taking care not to mess with any accessories.
Once youve undone the old belt, inspect it for signs of coolant or motor oil leaks, cracks, and breakage to uncover any underlying issues that are not Serpentine Belt-specific. Re-wind the new Serpentine Belt in the old ones place and re-activate the tensioner, tightening it with a wrench. Lastly, turn the engine on and idle it while inspecting its operation to ensure it runs smoothly.
