Shadow Engine Cooling Fan Controller is a vehicle engine thermostat with a temperature sensor. It not only monitors the cooling water temperature, but also allows users to set the startup temperature to keep the vehicle temperature constant and dissipate heat for the engine to maintain vehicle performance.

Shadow Engine Cooling Fan Controller prevents engine power decline.

The factory set the fan to start at 95℃~100℃. To let the electronic fan can be turned on earlier and reducing the chance of engine overheating and power decline, drivers can set the fan start-up temperature by themselves through Shadow engine cooling fan controller.

Shadow Engine Cooling Fan Controller with temperature monitoring function

Shadow Engine Cooling Fan Controller with monitoring and thermostat functions.

The digital automotive radiator fan controller combines the water temperature, oil temperature and voltmeter. It also has the function of temperature monitoring and can set warning values to assist the owner to monitor the vehicle. In response to different terrains and road conditions, it allows the user to operate the interface to adjust the temperature to achieve the purpose of improving engine performance. The control kit includes an operation interface setting unit, a signal feedback unit and a drive unit.

Signal Feedback Unit: Use a high-precision temperature sensor with an error of ±1% to return the temperature to the control interface unit for interpretation. Compared with commercially available fan controllers, our product is more sensitive and is about 15% faster than others. It also can monitor oil temperature and battery voltage at the same time.

Operation Interface Setting Unit: The user can read the current water temperature value through the operation interface and set the fan startup temperature. When the controller executes or stops the command, the numbers flash to prompt.

Drive Unit: After receiving the signal from the control unit, the 12V (30A) DC relay will conduct current to make the fan run. When the water temperature is 5°C lower than the set temperature, the fan will stop running immediately.

Shadow Engine Cooling Fan Controller dynamically adjusts according to driving conditions.

Shadow engine cooling fan controller uses adjustable resistors to make corrections according to different temperatures. As a result, engine temperature can be precisely controlled. Not only the operation interface but the product feedback can also be enhanced, so that adjustments can be made to suit the needs of the vehicle to maintain vehicle performance.

Shadow Engine Cooling Fan Controller maintains proper engine operating temperature.


Shadow develops products for original cooling fans. Therefore, to install the water temperature fan controller, just insert an extra temperature sensor and connect the control element to the original car fan to achieve the effect of early heat dissipation of the engine. The rate of heat dissipation will increase by 8.6%. It can effectively prevent the engine from overheating and is suitable for all 12V vehicles.


  • Can be set to start at a temperature of 70°C to 100°C.
  • Monitor water temperature, oil temperature and voltage at the same time.
  • Warning value setting. The number will start to flash to warn the driver when the specified value is reached.
  • Digital LED display increases data identification.

  • Oil Pressure Sensor Adaptor - It can read the oil temperature and pressure at the same time
    Oil Pressure Sensor Adaptor

    Oil pressure sensor adapter, which can also be called as oil filter sandwich plate adapter, is a kit connected to the oil filter element. This is where the oil circulating filters the oil impurities and can measure the pressure and temperature of the oil. The oil filter element can be divided into general type and paper. The oil adapter is suitable for general oil filter element. Most Japanese models, such as Toyota, Honda, Nissan, Mitsubishi, Mazda, Suzuki, Subaru and so on, use general filter elements. The thread of the oil filter element is divided into 3/4-16UNF and M20*1.5P. The general oil pressure sensor adapter is attached with two specifications of threads. GT86 adapter is higher than the other adaptor which have been specially developed for Subaru FA20,FA24(BRZ/GR86/WRX/Forester XT)、Honda L15B (CRV5/CIVIC 10 )、Honda K20C1(FK2/FK8)。In addition, oil pressure sensor adapter have been specially developed for European cars. For example, VAG Group's EA113 and EA211 engines are two engines. EA113 /2.0 TSI engine include car model: Audi A3/S3, Audi A4, Audi A6, Audi TT/TTS, VW Jetta, VW Golf GTI/R, VW Tiguan, VW Scirocco, VW Passat B6, SEAT Leon FR Mk2, SEAT Leon Cupra, SEAT Altea, SEAT Toledo Mk3, SEAT Exeo。EA211 /1.4 TSI engine include car model: Volkswagen Golf, Volkswagen Jetta, Volkswagen Passat, Skoda Octavia, Skoda Rapid, Skoda Superb, Audi A3, Audi A4。Above car models have corresponding oil pressure sensor adapter.
