Take the guesswork out of engine cooling. The Davies Craig #0444 Digital Thermatic® Fan Switch is the smartest way to manage your electric fans. Instead of using a simple, clunky mechanical switch, this digital controller gives you precise, push-button control with a clear LED display, ensuring your engine runs at the perfect temperature every time.

How to Fit Your Sensor

You have two easy ways to set up the probe, depending on how much precision you need:

• The Simple Way (Air Sensing): Simply slide the probe directly into the fins of your radiator. It’s the fastest, easiest method and doesn't require draining any coolant.
• The "Pro" Way (Coolant Sensing): For the most accurate temperature reading, we recommend placing the sensor directly inside your coolant flow. To do this, you can use our #409 Temperature Sensor Adaptor Kit (sold separately).
