16 in Electric Radiator Fan with Thermostat Kit - High Flow Cooling

In this review the BLACKHORSE-RACING 16 in electric radiator fan kit is evaluated for DIY mechanics and track-day enthusiasts who need a compact, high-flow auxiliary cooling solution. The bottom line: this kit combines a slim 16 in, 10-blade fan driven by a high torque motor and a simple 180 F thermostat switch to provide strong airflow and straightforward installation, making it most useful as a helper fan for radiators, oil coolers or condensers where space is limited.

Key Features

• 10-blade 16 in fan: The 16.05 in diameter fan with 10 blades is designed to move a lot of air while fitting into slimmer engine bays that lack clearance for deep fans.
• High torque motor: A sealed ball bearing motor and fully balanced blades reduce noise and increase durability for steady operation under load.
• Thermostat kit included: The wired thermostat turns the fan on at 180 F and off at 165 F, giving automatic temperature-controlled cooling without additional sensors.
• Slim design and reversible flow: At about 3.27 in thick the fan clears tight spaces and the blade and wiring can be reversed to make the unit a pusher or puller depending on application.
• Universal mounting: Mount brackets and tie straps are included so the fan can be fitted to radiators, oil coolers, transmission coolers and condensers on a broad range of vehicles.

Who It's For

This kit is aimed at car owners, hobby mechanics and small shop installers who need an affordable, compact auxiliary fan to assist the factory cooling system or replace a failed electric fan with a slimmer option. The automatic thermostat makes it suitable for commuters and weekend drivers who want set-and-forget temperature control without aftermarket controllers.

It may not be ideal for heavy continuous-duty racing applications where sustained peak cooling is required; some users report mixed results under extreme track conditions. Those needing fully variable speed control or integration with complex engine management systems should look for a dedicated variable-speed controller instead.

Pros & Cons

Pros

• Good airflow from a compact 16 in, 10-blade design that fits tight engine bays.
• Durable sealed ball bearing motor and balanced blades for quieter, long-life operation.
• Thermostat kit with 180 F turn-on simplifies wiring and automates operation.

Cons

• Cooling power receives mixed feedback in extreme track scenarios; may be better as a helper fan rather than the sole cooling solution.
• Instructions and wiring diagram are minimal, so installers should be comfortable with basic electrical wiring.

Specifications

Our Verdict

For most DIYers and garage mechanics the 16 in electric radiator fan kit is a solid value: it delivers strong airflow from a slim package, includes a practical thermostat switch, and uses a robust motor design. It works best as an auxiliary or replacement fan for everyday driving and moderate performance use, but those running extreme track schedules should evaluate more powerful or variable-speed systems.

Frequently Asked Questions

Can this fan be mounted as a pusher or puller?
Yes. The blade orientation and wiring can be reversed so the fan can operate as either an air pusher or a puller.

What temperature does the thermostat use?
The included thermostat is set to turn on at 180 F and turn off at 165 F and uses a 3/8 in NPT brass probe with a 1/2 in NPT adapter.

Is installation difficult for a home mechanic?
Basic mounting hardware and wiring are included, but instructions are minimal; someone comfortable with 12 V wiring should be able to install it without special tools.
