Davies Craig Digital Gauge Thermatic Fan / EWP Switch Kit 12v
A bright, attractive, compact high visibility 52mm round gauge with LED digital display for mounting in the driver’s compartment!
Automatically activates single or twin fans or a fan and Electric Water Pump at your set / targeted temperature when extra cooling is required. It can also be used to monitor transmission fluid temperature.
It senses air temperature as it passes through the radiator with the sensor placed in the radiator fin section or alternatively the sensor can also be placed directly into the coolant system in combination with a Temperature Sensor Adaptor Kit (Part 0409).
This unit can be configured to run at 24 volts by changing the relays to 24v, these are not supplied in the kit and must be purchased separately. Relays used are standard automotive relays.

PLEASE NOTE: The kit as supplied with a sensor designed to be placed between the vehicles radiator fins, an adapter kit is required to allow the sensor to be fitted into a coolant hose.
Air Temperature Application: In this application the sensor is placed into the vehicles radiator (hot coolant inlet side) directly sensing the air temperature as it passes through, this is ideal if you do not want to cut into any water / coolant hoses. However, this is the least accurate way of sensing temperature.
Water / Coolant Application: When purchased with the 'Temperature Sensor Adapter Kit 409' you can install the sensor into a hose putting the temperature sensor in direct contact with the coolant, this is the most accurate and preferred way to take your temperature reading. It is recommended to install the sensor in the return hose from the radiator.
Electric Water Pump Control: If using this switch for use with Davies Craig EWP's, it will not vary the speed of the pump in response to engine temperature but rather turn the pump on and off at your set temperature. For greater EWP control, we would recommend part number 8001 which can manage both the Electric Water Pump and your Electric Radiator Fans.
- This is a 12v only kit, if you intend to operate 24v fans you will need to purchase standard automotive 24v relays.
- Supplied with full installation instructions.
