Davies Craig DC-0448 Digital Thermatic Fan Switch Kit (12V/24V)

Take absolute control over your engine's cooling infrastructure with the premium Davies Craig DC-0448 Digital Thermatic Fan Switch Kit. This advanced electronic module functions as a highly accurate thermal controller, engineered to automatically manage the operation of one or two 12-volt or 24-volt electric cooling fans. By regulating airflow precisely when your engine demands it, this kit helps minimize parasitic engine drag, improves fuel efficiency, and guarantees stable operating temperatures under heavy street driving or demanding motorsport track conditions.

Dual Fan Operation & Smart Electrical Design

The DC-0448 controller features an intelligent dual-relay configuration capable of managing two separate electric fans. To protect your vehicle's electrical charging system from harsh current spikes, the module is programmed with a built-in 10-second startup delay. When the target temperature is reached, the first fan activates immediately; if additional cooling capacity is needed, the second fan safely engages 10 seconds later, preventing voltage drops and alternator strain.

Comprehensive Kit Inclusions & Installation Flexibility

This all-in-one thermal management solution gives you multiple ways to monitor your engine temperatures right out of the box:

• 1/8" NPT Threaded Sensor: Allows for direct, clean immersion into a thermostat housing, water neck, engine block, or inline hose adapter for the most accurate coolant temperature reads.
• Stainless Steel Temperature Probe: Alternatively, you can slide the probe directly between the aluminum fins of your radiator core to monitor air-side thermal changes without opening your cooling system.

Advanced Features & Built-In Air Conditioning Override

The unit features a clear, bright LED digital display that sits neatly inside your engine bay or cabin, showing both your real-time engine temperature and your user-defined set point. You can easily adjust the activation temperature across a wide range from 40°C to 110°C (104°F to 230°F) using simple push-button controls. Additionally, the wiring loom features a dedicated air conditioning override wire; when connected to your AC compressor clutch circuit, your cooling fans will automatically engage the moment your air conditioning is turned on, keeping condenser pressures low and cabin air ice-cold.
