Your INFINITI engine relies on a variety of intricate, connected parts that support the signature INFINITI ride you know and love. Some Engine 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 conduct power through and to the A/C compressor, power steering pump, alternator, and, in some cases, the water pump. Some people refer to the Serpentine Belt as a fan or accessory belt because it powers your INFINITI's peripheral devices. However, that simple reference doesn't make it any less important.
Serpentine Belts are usually made of ultra-sturdy rubber engineered to withstand the friction and heat of transferring power from one part of the engine to the next. However, like any other part, they are subject to wear and tear.
With age, Serpentine Belts can fray or crack or they can act up if soaked with oil or coolant. Also, they may lose tension, lack alignment, or slip because of malfunctioning tensioning systems, which may require replacing both the Serpentine Belt and the tensioner, or simply re-tensioning the belt, if it's still in working order. Some symptoms of Serpentine Belt problems are: rattling or squealing sounds coming from the engine, lackluster A/C or power steering performance, an overheated engine, and visible cracks or wear on the belt.
Typically, your INFINITI's Serpentine Belt is supposed to last hundreds or thousands of miles, but its life can be cut short due to lack of maintenance, oil leaks, and other issues. You should inspect your Serpentine Belt any time you change the oil, or an INFINITI expert can do it for you when you visit one of our service centers near you.
The Serpentine Belt replacement procedure 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, you'll need a Serpentine Belt replacement that fits your INFINITI model and year, and a specialized belt-tensioning tool. Note that if your INFINITI relies on a manual or hydraulic tensioner for the Serpentine Belt, visiting your nearest INFINITI service center is advisable.
When you're ready to get started, 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, ensuring not to mess with any accessories or pulleys!
Once you've undone the old belt, check it for signs of oil leaks, frays, and damage 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, tightening it with a wrench. Lastly, crank the engine and allow it to idle while inspecting its operation to ensure it runs smoothly.
