- 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 engine relies on a multitude of complex, interrelated parts that get you the characteristic Nissan drive you can't live without. Some Engine parts are linked by a series of belts, and the Serpentine Belt is among the most important ones.
The Serpentine Belt is a sturdy, cyclical strap that transfers power to the power steering pump, alternators, A/C compressors, and, in some cases, the water pump. Some refer to the Serpentine Belt as the accessory or fan belt because it powers the “peripheral devices” in your Nissan engine. However, you shouldn't underestimate its importance.
Nissan Serpentine Belts are typically made of reinforced rubber that's specially designed to endure the heat and friction involved in transferring energy from one engine component to the next. But, like other car parts, Serpentine Belts are subject to wear and tear.
Serpentine Belts can tear or crack with age, or they can malfunction if they become soaked due to oil or coolant leaks. Also, they may lose tension, lack alignment, or slip due to faulty tensioning mechanisms, which may result in needing to replace both the tensioner and the Serpentine Belt, or recalibrating the belt, if possible. Common signs of Serpentine Belt issues include: weird rattling noises coming from the engine, a malfunctioning car A/C or loss of power steering functionality, engine overheating, and visible signs of wear on the belt.
In general, your Nissan Serpentine Belt is one of your most long-lasting parts, but its useful life can be shortened due to coolant leaks, oil leaks, and old tensioners. You should get your Serpentine Belt inspected when you change your oil, or get a professional opinion from one of the Nissan experts at a service center near you.
The required method for a Serpentine Belt replacement 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.
In most cases, you'll need a Serpentine Belt replacement that fits your Nissan model and year, and a specialized belt-tensioning tool. If your Nissan has a hydraulic or manual tensioner mechanism, getting a Serpentine Belt replacement at a Nissan service center near you is highly recommended.
When you're prepared to begin, take pictures of the placement of your current Serpentine Belt and of how it intertwines with other engine components. 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 removed the old Serpentine Belt, inspect it for signs of coolant or motor oil leaks, cracks, and damage 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, using a wrench to tighten it to the appropriate level. Lastly, turn the engine on and idle it while you observe the new belt's operation to ensure it is installed correctly.
Whether you choose to replace the Serpentine Belt yourself or get professional services from a Nissan expert near you, having the right Nissan part is essential.
