Your INFINITI's motor depends on various complicated, connected parts that help you enjoy that smooth INFINITI ride you love! Many Engine components connect through a network of belts, and one of the most important belts is the Serpentine Belt.

The Serpentine Belt is a sturdy, cyclical strap that conduct power through and to the alternator, power steering pump, car A/C compressor, and, in some cases, the water pump. Sometimes the Serpentine Belt is called an accessory belt because it powers your INFINITI's peripheral devices. However, that simple reference doesn't make it any less important.

INFINITI Serpentine Belts are typically made of reinforced rubber that's specially designed to endure the heat and friction involved in transporting power from one engine component to the other. 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. Additionally, they can slip, lose tension, or become misaligned 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: rattling or squealing sounds coming from the engine, a malfunctioning car A/C or loss of power steering functionality, engine sweltering, and visible cracks or wear on the belt.

Generally, your INFINITI Serpentine Belt is one of your most long-lasting parts, but its useful life can be shortened due to coolant leaks, oil leaks, and old tensioners. 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 process of replacing your INFINITI Serpentine Belt depends on the type of tensioner you're dealing with. 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. Note that if your INFINITI relies on a manual or hydraulic tensioner for the Serpentine Belt, it may be a smarter choice to visit your nearest INFINITI experts for professional assistance.

When you're ready to get started, 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 unravel the Serpentine Belt, avoiding displacing any pulleys or accessories.

Once the old Serpentine Belt is out, inspect it for signs of coolant or motor oil leaks, tears, and damage to pinpoint issues that go beyond-the-belt! Re-wind the new Serpentine Belt in the old one's place and re-activate the tensioner, adequately tightening it with a wrench. Lastly, turn the engine on and idle it 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 services from an INFINITI expert near you, having the right INFINITI part is essential.
