INFINITI Belts, Pulleys & Brackets - Genuine OEM Parts

The Faulkner INFINITI of Willow Grove parts team has all the parts you're looking for your restoration, modification, or repair project. Belts, pulleys, and brackets form an integrated system that transfers power from your crankshaft to essential accessories throughout the engine bay. The serpentine belt routing system drives components including alternators, power steering pumps, air conditioning compressors, and cooling fans with precise timing and tension. When any component in this system fails, you risk losing critical vehicle functions that affect safety, comfort, and drivability.

Understanding Belt System Operation

The serpentine belt connects your crankshaft pulley to multiple accessory components through a carefully engineered routing pattern that maximizes efficiency. Automatic tensioner assemblies maintain proper belt tension as components wear and belts stretch during normal operation. Your M37 uses sophisticated tensioning systems designed to handle varying loads from high-performance accessories and climate control demands. Idler pulleys guide the belt through complex routing paths while providing additional contact surface for improved grip and longevity. Mounting brackets secure each component to precise locations that maintain proper alignment and prevent vibration.

Identifying Belt System Problems

Serpentine belts deteriorate from constant flexing, exposure to engine heat, and contamination from fluid leaks throughout the engine bay. Most belts require replacement every 70,000 to 90,000 miles, though severe driving conditions can accelerate wear patterns. Pulleys develop bearing wear that creates squealing noises and allows wobbling that damages belts prematurely. Tensioner failure results in insufficient belt pressure, causing slippage and reduced accessory performance. QX56 owners should inspect belt condition regularly, as larger engines place additional stress on drive components and alternators.

Why Choose Genuine INFINITI Belt Components

Genuine INFINITI belts use specialized rubber compounds and reinforcement materials engineered for your engine's specific power output and accessory requirements. Original equipment pulleys feature precision bearings and balanced construction that minimize vibration while maximizing component lifespan. Aftermarket alternatives often use substandard materials that fail early or create noise and vibration issues during operation. Our genuine brackets maintain exact component positioning and alignment, preventing accelerated wear and ensuring smooth power transfer to all engine accessories without compromising performance or reliability.
