OEM repacement mechanical radiator fan blade fits all early 2002+ Infiniti G35 models equipped with a mechanical fan.  After years of heat and stress the original fan blades often develop stress cracks around the blades. This can become dangerous because as they contine to age they may come apart and damage the radiator, hoses, and wiring for engine management systems.  

We also recommend considering changing the fan clutch that this fan blade mounts to. This ensures years of trouble-free use.
