Designed for universal fitment, the fan delivers up to 3,000 CFM and includes a thermostat that turns the fan on at 180°F and off at 165°F, plus a relay and wiring harness for safer, reliable switching. Blades and wiring can be reversed so the unit functions as either a pusher or puller depending on your mounting preference.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this fan fit my vehicle and mounting setup?\u003c\/h3\u003e\n\u003cp\u003eThe STMGW 16\" fan is built for universal use and is compatible with most radiators and cooling cores. It mounts using standard fan brackets or zip-tie systems and works well in tight engine bays because it offers reversible airflow and a slim profile. The included 3\/8\" NPT brass probe with a 1\/2\" NPT adapter lets you position the thermostat sensor where it reads coolant or ambient air temperature accurately.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUniversal bracket-friendly design for radiators, condensers and coolers\u003c\/li\u003e\n  \u003cli\u003eReversible blade\/wiring orientation for pusher or puller setup\u003c\/li\u003e\n  \u003cli\u003eIncludes 3\/8\" NPT probe and 1\/2\" adapter for flexible sensor placement\u003c\/li\u003e\n  \u003cli\u003eCompact mounting footprint suits tight engine compartments\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat performance can I expect from the motor and blades?\u003c\/h3\u003e\n\u003cp\u003eThe kit uses a high-torque motor with sealed ball bearings and fully balanced S-curved blades to deliver efficient airflow at low noise. Rated at 120 watts, the motor can spin up to about 2,000 RPM and the assembly offers a maximum airflow around 3,000 CFM under optimal conditions. Balanced construction and sealed bearings contribute to reduced vibration and longer operational life.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e120 W high-torque motor with sealed ball bearings for durability\u003c\/li\u003e\n  \u003cli\u003eReversible 10 S-curved wide blades for maximum airflow\u003c\/li\u003e\n  \u003cli\u003eMaximum ~3,000 CFM and ~2,000±10% RPM performance range\u003c\/li\u003e\n  \u003cli\u003eFully balanced blades reduce noise and vibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the thermostat, relay, and wiring improve reliability and control?\u003c\/h3\u003e\n\u003cp\u003eThis kit’s thermostat probe activates the fan at 180°F and deactivates it at 165°F, offering automated temperature control that prevents unnecessary runtime. A dedicated relay handles the motor’s current draw so vehicle switches and circuits are protected, while the wiring harness simplifies installation and reduces the chance of wiring errors. The brass thread-in probe provides a stable, repeatable temperature signal for consistent operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThermostat turns on at 180°F and off at 165°F for automatic operation\u003c\/li\u003e\n  \u003cli\u003eIncluded relay protects vehicle circuits and handles motor current\u003c\/li\u003e\n  \u003cli\u003eThread-in 3\/8\" NPT brass probe with 1\/2\" adapter for secure sensor mounting\u003c\/li\u003e\n  \u003cli\u003eWiring harness simplifies installation and reduces electrical stress\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The STMGW 16\" Electric Radiator Fan Kit is ideal for mechanics, DIY enthusiasts and custom builders who need a reliable, high-flow cooling solution for performance engines, retrofit projects and cooling upgrades.
