16in Curved Blade Fan250 0 CFM

The 16in Curved Blade Fan by FLEX-A-LITE (Model 105317) is a heavy-duty electric cooling fan engineered for serious automotive builders and mechanics who demand reliable thermal management in custom engine bays. Whether you're upgrading a street machine, hot rod, or performance truck, this curved blade design delivers 2500 CFM of airflow to prevent coolant temperature creep during high-load driving or stationary operation. Built for both push and pull configurations, this fan adapts to tight spaces where traditional fixed fans fall short, making it an essential upgrade for street-driven and competition vehicles alike.

The 16in curved blade design maximizes airflow efficiency by directing cooling air through the radiator core at optimal velocity and volume—2500 CFM is substantial enough to handle high-horsepower engines or restrictive radiator configurations without requiring excessive electrical draw. Operating at 12V, this fan integrates seamlessly into modern wiring harnesses or classic vehicles retrofitted with updated electrical systems. The plastic blade construction keeps weight to just 6.8 lbs, reducing parasitic drag and heat soak in the engine compartment while maintaining durability under continuous operation. Its push/pull capability means you can mount it ahead of the radiator (pull) or behind it (push), giving fabricators flexibility in cramped engine compartments where space is at a premium.

This curved blade fan suits vintage restorations, LS engine swaps, big-block builds, and any application where stock cooling proved inadequate or space constraints ruled out larger traditional setups. Mechanics frequently specify this model for high-altitude operation, desert racing, or vehicles running tight underhood packaging where every inch counts. The 15.75 x 16.625 inch blade diameter and 4-inch depth make it compatible with most aftermarket and OEM radiator supports, though verification against your specific mounting location is always recommended before purchase. Pair this with a quality fan shroud and proper wiring to a thermostat switch for intelligent operation that activates only when needed, maximizing fuel economy while guaranteeing your engine stays cool.
