STMGW 16" Electric Radiator Fan Kit with Thermostat Probe — 10-Blade Reversible, 3,000 CFM

STMGW 16-inch electric radiator fan kit is a complete universal cooling solution that includes a reversible 10-blade fan, 180°F/165°F thermostat probe, relay, and wiring harness for plug-and-play engine, radiator, condenser, or oil/transmission cooler applications.

This kit combines a high-torque, sealed-ball-bearing 120 W motor with wide S-curved blades and a temperature-controlled switch assembly so you can add dependable, low-noise electric cooling to cars, trucks, project vehicles, or aftermarket cooling systems. The fan is reversible (push or pull), mounts to universal brackets, and delivers up to 3,000 CFM at around 2,000 RPM. A threaded brass temperature probe and adapter are included for straightforward installation and automatic on/off control.

How does the thermostat wiring switch control the fan?

The kit includes a temperature switch set to turn the fan on at 180°F and off at 165°F, giving a simple automatic control based on coolant or radiator temperature. The thread-in brass probe reads temperature and actuates the relay so the fan starts only when needed, minimizing battery drain.

• 180°F turn-on, 165°F turn-off preset temperatures
• 3/8" NPT brass probe with 1/2" NPT adapter for common ports
• Wiring harness with relay for safe high-current switching
• Mounts to radiator, condenser, or auxiliary cooler sensor ports

What performance can I expect from the 16" reversible fan?

The 16-inch fan uses ten wide S-curved blades and a balanced assembly to move up to 3,000 CFM while keeping noise and vibration low. The sealed ball-bearing motor provides durable, high-torque operation with a rated maximum speed near 2,000 RPM for effective cooling under load.

• Maximum airflow: 3,000 CFM for strong heat dissipation
• Motor power: 120 watts for reliable continuous operation
• Balanced 10-blade design for reduced vibration and noise
• Reversible blade/wiring setup allows push or pull configurations

Which vehicles and systems is this fan kit compatible with?

This STMGW fan kit is built for universal fitment, suitable for radiators, oil or transmission coolers, condensers, and custom cooling setups. Its reversible design and included hardware make it adaptable to most front-mounted or auxiliary cooler positions on cars, trucks, and off-road rigs.

• Universal mounting options for radiators and condensers
• Works with oil and transmission cooler installations
• Reversible operation for push or pull mounting needs
• Includes probe and adapter for common temperature ports

How difficult is installation and what’s in the box?

Installation is designed to be approachable for DIYers and professional installers alike: the kit ships with a prewired fan motor, thermostat switch with probe and adapter, relay and wiring harness, and mounting hardware options. Basic tools and a mounting location with a threaded port or bracket are all you need to complete the job.

• Included brass 3/8" NPT probe plus 1/2" NPT adapter
• Relay and wiring harness for safe electrical control
• Preassembled 16" 10-blade fan with sealed ball bearings
• Reversible blade/wiring configuration and universal brackets

Who is this for: The STMGW 16" Electric Radiator Fan with Thermostat Wiring Switch Relay Kit is ideal for car and truck owners upgrading cooling performance, builders of custom or track cars, and mechanics looking for a reliable aftermarket fan option for radiators, condensers, and auxiliary coolers. If you want a universal, thermostatically controlled fan with strong airflow, low noise, and durable bearings for long life, this kit gives the components you need to add automatic electric cooling to most vehicles and systems.
