The fan mounts using a 5\/8\" pilot hole and a common bolt pattern, making it straightforward to fit many fan clutches or pulley-driven setups. It ships as a single unit and includes a 90-day limited factory warranty.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this fan improve cooling under heavy load?\u003c\/h3\u003e\n\u003cp\u003eThe six blades with a steep 27° pitch are shaped to generate strong axial airflow at operating speeds typical of belt-driven mechanical fans. That focused airflow helps reject engine heat through the radiator when natural vehicle movement or electric fans aren’t sufficient.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e27° blade pitch for increased air displacement\u003c\/li\u003e\n  \u003cli\u003eSix blades for consistent, continuous airflow\u003c\/li\u003e\n  \u003cli\u003eSteel construction resists flexing at high RPM\u003c\/li\u003e\n  \u003cli\u003eDesigned to work with clutch or pulley-driven arrangements\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my vehicle and mounting setup?\u003c\/h3\u003e\n\u003cp\u003eThe fan uses a universal bolt pattern centered on a 5\/8\" pilot hole, which is compatible with many common mechanical fan clutches and mounting hubs.
