The dual 16\" SPAL fans provide strong airflow support across a broad section of the radiator when vehicle speed alone cannot move enough air through the cooling package.\u003c\/p\u003e\n\u003ch3\u003eDoes 3,836 CFM guarantee that the engine will stay cool?\u003c\/h3\u003e\n\u003cp\u003eNo. Fan airflow is only one part of the system. Cooling performance also depends on radiator size, shroud coverage, coolant flow, thermostat operation, system pressure, hose routing, water-pump speed, engine tune, airflow entry, and the ability to discharge hot air from the chassis.\u003c\/p\u003e\n\u003ch3\u003eWhy is a full fan shroud important?\u003c\/h3\u003e\n\u003cp\u003eA properly fitted shroud helps the fans pull air through a larger portion of the radiator core instead of only through the area directly in front of the fan blades. Better core coverage improves low-speed cooling efficiency and reduces dead-air areas.\u003c\/p\u003e\n\u003ch3\u003eWhat electrical system is required for the fans?\u003c\/h3\u003e\n\u003cp\u003eEach fan draws approximately 17.4–19.5 amps, so the combined running load can approach 39 amps. The fans should be wired with correctly sized relays, fuses, wiring, grounds, and charging-system capacity. Startup current may be higher than the stated running draw.\u003c\/p\u003e\n\u003ch3\u003eCan both fans run from one relay?\u003c\/h3\u003e\n\u003cp\u003eThe electrical system should be sized for the combined current demand and startup load. In many custom installations, each fan is placed on its own appropriately rated relay and fuse so one circuit failure does not disable both fans.\u003c\/p\u003e\n\u003ch3\u003eAre -16 AN coolant lines large enough?\u003c\/h3\u003e\n\u003cp\u003eThis radiator is configured with -16 AN upper and lower connections because that plumbing size is commonly used in WOD race and custom chassis cooling systems. The complete cooling system must still be designed around the engine, water pump, hose length, routing, restrictions, and intended operating conditions.\u003c\/p\u003e\n\u003ch3\u003eWhere should the radiator be mounted?\u003c\/h3\u003e\n\u003cp\u003eThe radiator should be positioned where it receives a reliable supply of cool air and has a clear path for hot air to exit. Rear-mounted radiators often require carefully designed ducting, body vents, fan controls, and hose routing to prevent heat recirculation and trapped air.\u003c\/p\u003e\n\u003ch3\u003eHow should the radiator be mounted in a tube chassis?\u003c\/h3\u003e\n\u003cp\u003eThe radiator should be securely supported while allowing some isolation from chassis twist and vibration. Hard-mounting a large aluminum radiator into a flexing chassis can place unnecessary stress on the tanks, welds, fittings, and core.\u003c\/p\u003e\n\u003ch3\u003eWhat should be checked before ordering?\u003c\/h3\u003e\n\u003cp\u003eMeasure the available width, height, radiator thickness, fan depth, hose clearance, fill-cap access, mounting structure, and airflow path.
