About this item
  • [Universal Compatibility] This dual fan relay kit is designed for universal fitment, working seamlessly with 10, 12, 14, and 16 inch cooling fans. It supports all 12V systems across a wide range of vehicles, including cars, trucks, hot rods, and performance vehicles. Whether used with single or dual cooling fans, this kit is an ideal solution for aftermarket electric fan installations, electric cooling fan thermostat setups, or as a direct replacement for damaged wiring and faulty relays.
  • [Automatic Cooling Control for Engine Protection] Equipped with a thermostat switch that activates the fans at 185°F and shuts them off at 175°F, this radiator fan relay kit helps maintain a safe and consistent engine temperature. This automatic control system provides reliable protection against overheating during demanding conditions such as towing, racing, or stop-and-go city driving.
  • [Simple Installation with Clear Wiring Guidance] The electric radiator fan kit can be installed in minutes by following the included wiring diagram. The straightforward setup requires connecting RED to battery positive (12VDC), COFFEE to fan positive, BLACK to ignition, and GREY to the temperature switch or sending unit, allowing for a hassle-free installation process.
  • [Complete Package with All Necessary Components] This electric fan mounting kit comes with everything needed to wire and control dual electric fans. The package includes 2pcs wiring harnesses, 2pcs 40A relays, one 3/8" NPT threaded thermal switch, one 1/2" NPT adapter thermostat switch (185°F on / 175°F off), a wiring diagram, 2pcs 20amp fuses, 8pcs ring terminals, 4pcs wiring connectors, and 2pcs spade connectors—providing a comprehensive solution for your cooling system needs.
  • [Important Installation Note] For proper operation, the radiator fan switch thermostat must be grounded to the engine through its threads. Additionally, ensure that the engine itself is properly grounded to ensure the system functions correctly and delivers reliable cooling performance.
