Universal 16-Inch Cooling Fan
The STMGW UB3180 is a 16-inch electric radiator fan built for automotive cooling systems. It suits classic engines, hot rods and modern vehicles needing extra airflow across radiators, oil coolers or condensers. The kit includes a thermostat, relay, circuit breaker and full wiring harness for direct installation.
Sustained Airflow Performance
A 120-watt motor draws 11 amps at 12 volts to deliver 3000 CFM at 2000 RPM under continuous load. The high-torque design uses sealed ball bearings and fully balanced reversible S-curved blades to maintain steady output without fading during extended operation. Blade direction can be switched between puller and pusher configurations.
Thermal Control and Power Draw
An included thread-in thermostat activates the fan at 180°F and shuts it off at 165°F, managing engine temperature automatically. The 3.27-inch thick housing fits tight engine bays while the 40-amp relay and 30-amp breaker protect the electrical system during peak demand. Sealed bearings keep operational noise low throughout the duty cycle.

Questions about this item
How much current does the 120 watt motor draw when the fan runs continuously?
The motor draws 11 amps at 12 volts, so a 12 volt supply capable of at least 11 amps is needed for all-day operation.
Does the included relay kit provide everything required to wire the fan to a 12 volt system?
Yes, the package supplies a 40 amp relay, a 30 amp circuit breaker, a wiring harness with mount, ring terminals, butt connectors and mounting screws.
Will the 16 inch, 3.27 inch thick fan fit alongside an existing radiator that uses 3/8 inch NPT sensor ports?
The kit includes a 3/8 inch NPT thread-in thermostat probe and a 1/2 inch NPT adapter, so it can share the same port style as the older radiator.
