Universal 10" Slim Electric Radiator Cooling Fan Kit (2 Fans) with Thermostat Relay Wiring Kit 12V 800 CFM 185°F On

High-Flow Dual 10-Inch Slim Electric Radiator Fan Kit with Thermostat Relay Harness for Universal 12V Applications

What it Does: The Universal 10-Inch Slim Electric Radiator Cooling Fan Kit provides supplemental or primary electric airflow, pulling up to 1,600 CFM across the core to maintain stable coolant temperatures under heavy thermal load.

The Stock Mechanical Fan Limitation

OEM belt-driven clutch fans rob crankshaft horsepower, generate parasitic drag, and suffer severe airflow drop-off at low engine RPM or during prolonged idle. Furthermore, bulky factory mechanical shrouds trap ambient heat in tight engine bays, accelerating heat soak and driving up coolant temperatures in modified V8 builds, heavy tow rigs, and street rods operating in stop-and-go traffic.

The Engineering Solution

This dual electric cooling system utilizes low-profile, 2.36-inch slim shrouds and 6-blade curved impellers delivering 800 CFM per fan (1,600 CFM combined) at 2,400 RPM. Engineered with high-torque 80W 12V motors, this kit operates independently of engine speed. The automated thermostatic circuit utilizes a brass 3/8-inch NPT probe engaging the fans at 185°F and shutting off at 175°F. Electrical protection is managed via a heavy-duty 40A relay harness and a 30A auto-reset circuit breaker to prevent thermal overload.

Frequently Asked Questions & Fitment Warnings

Does this fit custom or OEM core supports?

Yes, this kit mounts universally to any radiator core using the included nylon through-core tie straps, provided there is at least 2.36 inches of clearance between the core and engine accessories.

How is the thermostatic harness wired?

Connect red to 12V battery power, white to keyed ignition switched 12V, black to the 3/8-inch NPT temperature switch, and blue to the fan positive leads.
