Your INFINITI engine relies on a multitude of complex, interrelated parts that support the signature INFINITI ride you know and 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 transfers power to the power steering pump, alternators, A/C compressors, and, in some models, the water pump. Some refer to the Serpentine Belt as the accessory or fan belt because it engages your INFINITI engine's peripheral devices. However, that simple reference doesn't make it any less important.
Serpentine Belts are usually made of ultra-sturdy 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 fray, crack, or even peel with age, or they can act up if soaked with oil or coolant. They can also lose alignment, slip, or lack tension, because of faulty tensioners, which may require replacing both the Serpentine Belt and the tensioner, or recalibrating the belt, if possible. A few signs that you might have Serpentine Belt problems include: engine rattling noises, subpar air conditioning or steering capabilities, engine overheating, and visible cracks or wear on the belt.
Typically, your INFINITI 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. 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 required method for a Serpentine Belt replacement depends on the type of tensioner you're dealing with. Accordingly, you should check your INFINITI owner's manual before attempting any part replacements at home.
Without a doubt, you'll need a Serpentine Belt replacement that fits your INFINITI model and year, and a specialized belt-tensioning tool. Remember that if your INFINITI has a manual or hydraulic Serpentine Belt tensioner, it may be a smarter choice to visit your nearest INFINITI experts for professional assistance.
When you're prepared to begin, take a photo of your Serpentine Belt's current positioning and how it winds around your engine's components. Then, detach the tensioner using a ratchet and gently unwind the Serpentine Belt, taking care not to mess with any accessories.
Once the old Serpentine Belt is out, check it for signs of engine oil or coolant leaks, tears, and wear to uncover any underlying issues that are not Serpentine Belt-specific. Thread the new Serpentine Belt back into place and release the tensioner, tightening it with a wrench. Finally, turn your vehicle on and let the engine idle while you observe the new belt's operation to ensure it is installed correctly.
