Your INFINITIs motor depends on various complicated, interconnected components that help you enjoy that smooth INFINITI ride you love! Some parts are linked by a series of belts, and one of the most important belts is the Serpentine Belt.
The Serpentine Belt is a sturdy, continuous belt that transmits power through and to the alternator, power steering pump, car A/C compressor, and, in some models, to the water pump, too. Some people refer to the Serpentine Belt as a fan or accessory belt because it powers the peripheral devices in your INFINITI engine. However, that simple reference doesnt make it any less important.
Serpentine Belts are usually made of ultra-sturdy rubber manufactured to withstand the challenges involved in transferring energy from one engine component to the next. But, like all good things, even Serpentine Belts dont last forever!
With age, Serpentine Belts can fray or crack or they can malfunction if they become soaked due to oil or coolant leaks. They can also lose alignment, slip, or lack tension, because of faulty tensioners, which may necessitate Serpentine Belt and tensioner replacements, or recalibrating the belt, if possible. A few signs that you might have Serpentine Belt problems include: engine rattling noises, a malfunctioning car A/C or loss of power steering functionality, engine overheating, and apparent signs of wear like cracks on the belt.
Typically, your INFINITIs Serpentine Belt is supposed to last hundreds or thousands of miles, but issues like oil leaks and worn tensioner mechanisms can significantly shorten its lifespan. You should get your Serpentine Belt inspected when you change your oil, 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. Consult with an expert technician or your INFINITI manual before DIY-ing any services!
In most cases, youll need a Serpentine Belt replacement that fits your INFINITI model and year, and a belt tensioner tool. Remember that if your INFINITI has a manual or hydraulic Serpentine Belt tensioner, visiting your nearest INFINITI service center is advisable.
When youre prepared to begin, take pictures of the placement of your current Serpentine Belt and of how it winds around the motors different parts. Then, use a ratchet to release the tensioner and gently unravel the Serpentine Belt, taking care not to mess with any accessories.
Once youve removed the old Serpentine Belt, check it for signs of engine oil or coolant leaks, frays, and damage to pinpoint issues that go beyond-the-belt! Thread the new Serpentine Belt back into place and release the tensioner, tightening it with a wrench. Lastly, turn the engine on and idle it while visually ensuring that the new belt runs smoothly.
Whether you decide to replace your INFINITI Serpentine Belt at home or get professional services from an INFINITI expert near you, ensuring proper fitment of all your replacement parts is crucial.
