INSTALLATION VIDEO
  1. One Fan or Two?

    The Davies Craig Universal Fan Switch can run a single or dual fan application. The second fan (if applicable) will start 5 seconds after Fan #1 runs. 

  2. Coolant Temperature Sensor 

    Direct coolant measurement via the included 1/4" or 1/8" NPT sensor, ideal for thermostat housing, radiator, engine block or inline adapter. The kit also includes the standard fin probe.

  3. Digital Fan Switch Operation 

    Fan 1 will start at the set temperature. Fan 2 will start 5 seconds later. Both fans will operate until the temperature has been reduced to 5°C (9°F) below your set temperature.

  4. Why Upgrade? 

    The GEN II isn’t just an update—it’s a complete usability and performance improvement on the original dual relay fan switch. With smarter control, faster response, and a more installer-friendly design, it delivers everything needed for modern cooling systems.
