- 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, connected parts that help you enjoy that smooth Nissan ride you 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, continuous belt that transfers power to the power steering pump, alternators, A/C compressors, and, in some models, the water pump. Sometimes the Serpentine Belt is called an accessory belt because it engages your Nissan engine's peripheral devices. However, you shouldn't underestimate its importance.
Serpentine Belts are generally made of tough-but-flexible rubber that's specially designed to endure the heat and friction of transferring power from one part of the engine to the next. However, like any other part, they are subject to wear and tear.
Serpentine Belts can tear or crack with age, or they can act up if soaked with oil or coolant. They can also lose alignment, slip, or lack tension, 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, an overheated engine, and visible cracks or wear on the belt.
Generally, your Nissan Serpentine Belt can last many thousands of miles, but its life can be cut short due to lack of maintenance, oil leaks, and other issues. You should get your Serpentine Belt inspected when you change your oil, or get a professional inspection from a Nissan service center in your area.
The Serpentine Belt replacement procedure depends on the type of tensioner you're dealing with. Accordingly, you should check your Nissan owner's manual before attempting any part replacements at home.
Without a doubt, you'll need a Serpentine Belt replacement that fits your Nissan model and year, and an adequate belt tensioner. If your Nissan has a hydraulic or manual tensioner mechanism, visiting your nearest Nissan service center is advisable.
When you're prepared to begin, snap a photo of your belt's current placement and of how it winds around the motor's different parts. Then, use a ratchet to release the tensioner and gently unwind the Serpentine Belt, avoiding displacing any pulleys or accessories.
Once the old Serpentine Belt is out, check it for signs of oil leaks, tears, and damage to identify any other issues that may not be resolved by just replacing the belt! Thread the new Serpentine Belt back into place and release the tensioner, using a wrench to tighten it to the appropriate level. Finally, turn your vehicle on and let the engine idle while visually ensuring that the new belt runs smoothly.
Whether you decide to replace your Nissan Serpentine Belt at home or get professional replacement services at your local Nissan service center, getting the right parts for the job is vital!
