Your INFINITI's motor depends on various complicated, interrelated parts that help you enjoy that smooth INFINITI ride you love! Some Engine parts are linked by a series of belts, and the Serpentine Belt is among the most important ones.
Your INFINITI Serpentine Belt is a sturdy, continuous belt that transmits power through and to the A/C compressor, power steering pump, alternator, and, in some models, water pump. Some people refer to the Serpentine Belt as a fan or accessory belt because it powers your INFINITI's peripheral devices. But, don't underestimate its importance.
Serpentine Belts are generally made of tough-but-flexible rubber manufactured to withstand the challenges involved in transporting power from one engine component to the other. But, like all good things, even Serpentine Belts don't last forever!
Serpentine Belts can fray, crack, or even peel with age, or they can act up if soaked with oil or coolant. Additionally, they can slip, lose tension, or become misaligned due to faulty tensioning mechanisms, which may require replacing both the Serpentine Belt and the tensioner, or recalibrating the belt, if possible. Some symptoms of Serpentine Belt problems are: rattling or squealing sounds coming from the engine, subpar air conditioning or steering capabilities, engine overheating, and visible signs of wear on the belt.
In general, your INFINITI's Serpentine Belt is supposed to last hundreds or thousands of miles, but its useful life can be shortened due to coolant leaks, oil leaks, and old tensioners. It's a good idea to inspect your Serpentine Belt during every oil change, or get a professional opinion from one of the INFINITI experts at a service center near you.
The process of replacing your INFINITI Serpentine Belt varies depending on the type of tensioner mechanism it relies on. Consequently, it's best to check your INFINITI's manual before replacing the Serpentine Belt yourself.
Without a doubt, you'll need a Serpentine Belt replacement that fits your INFINITI model and year, and an adequate belt tensioner. If your INFINITI has a hydraulic or manual tensioner mechanism, getting a Serpentine Belt replacement at an INFINITI service center near you is highly recommended.
Once you're all set up, snap a photo of your belt's current placement and of how it winds around the motor's different parts. Then, release the tensioner using a ratchet and gently unravel the Serpentine Belt, avoiding displacing any pulleys or accessories.
Once you've removed the old Serpentine Belt, check it for signs of engine oil or coolant leaks, frays, and breakage to uncover any underlying issues that are not Serpentine Belt-specific. Re-thread a new Serpentine Belt in the old one's place and release the tensioner, adequately tightening it with a wrench. Lastly, crank the engine and allow it to idle 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 replacement services at your local INFINITI service center, ensuring proper fitment of all your replacement parts is crucial.
