Engine Cooling Fan Controller

Engine Cooling Fan Controller

Engine Cooling Fan Controller can Coolant Engine Fastly.
Engine Cooling Fan Controller can Coolant Engine Fastly.

Engine Cooling Fan Controller is equipped with two channels of sensors which can detect the temperature of cooling water temperature and lubricating oil temperature. It is displayed by a seven-segments display with a 1/8NPT temperature sensor.

Engine Cooling Fan Controller can be set up from 70°C ~ 100°C and also can set the warning value memory function. A warning light will show up once it reached the setting value and drive the 12V DC relay to conduct current then turn on the engine cooling fan, it will stop operating when the temperature is lower 5°C than the specified temperature.

Engine cooling fan controller can operate before 105°C earlier than the original vehicle fan in order to increase the engine heat dissipation efficiency. It can keep the parts of the vehicle engine room below 100°C which can prevent the components from cracking or aging due to high temperature.


  • AUTO JAW extracts the cooling fan of the original vehicle for product development. We know that the cooling system of plays an important role in the safety and performance of the vehicle. Engine cooling fan controller does not require excessive disassembly and modification of the engine parts of the vehicle. It only needs to insert a temperature sensor and connect the control element to the fan of original vehicle to start the heat dissipation before the original setting and increase the heat dissipation rate to 43%. It is suitable for all 12V vehicles.


  • Engine cooling fan controller can be controlled to start at 70°C ~ 100°C.
  • Monitor water temperature, oil temperature and voltage at the same time.
  • Warning set with number flashing as warning signal.

  • 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. 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.
