Made from high-quality steel, this pulley offers strength and resistance to wear, helping to extend the life of your belt system. Its black coating provides additional protection against rust and environmental factors. The pulley’s dimensions—84 mm outside diameter, 25 mm width, and 37 mm inside diameter—are tailored to fit specific Nissan vehicles, including the Altima, Frontier, Maxima, Murano, Quest, and Xterra. The single mounting hole and smooth pulley surface (no grooves) are designed to work seamlessly with the serpentine belt type used in these models. The included bearing with a 12.2 mm width supports smooth rotation and reduces friction, contributing to quieter and more efficient engine operation.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestores proper serpentine belt tension and alignment\u003c\/li\u003e\n\u003cli\u003eEliminates belt slippage and squealing noises\u003c\/li\u003e\n\u003cli\u003ePrevents premature belt wear caused by misaligned pulleys\u003c\/li\u003e\n\u003cli\u003eReplaces worn or damaged idler pulleys to maintain accessory drive system performance\u003c\/li\u003e\n\u003cli\u003eHelps avoid engine overheating by ensuring proper operation of belt-driven components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify compatibility with your Nissan model before installation\u003c\/li\u003e\n\u003cli\u003eInspect the serpentine belt for wear and replace if necessary during pulley installation\u003c\/li\u003e\n\u003cli\u003eUse proper tools to remove and install the pulley to avoid damage\u003c\/li\u003e\n\u003cli\u003eEnsure the mounting hole aligns correctly and the pulley spins freely after installation\u003c\/li\u003e\n\u003cli\u003eFollow vehicle manufacturer torque specifications for mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDorman manufactures the 419-625 idler pulley to meet or exceed OEM standards for fit, form, and function.
