When the cooling water temperature reaches a certain point, in order to avoid possible risks, the ECU will make several changes including fuel increase and retarding the ignition point which will cause a reduction of power. J's Racing has designed a low temperature thermal swith which will maintain the maximum horsepower by keeping the temperature of the cooling water at around 75°C - 80°C. It will activate the fan at 80°C instead of 95°C and fully utilizes the water characteristics of high specific heat. Water changes temperature less when it is absorbed or loses a given amount of heat. As a result, it works toward preventing power loss, knocking and various thermal negative effects. It works well for all types cooling systems from the stock radiator to multi layer racing radiators.
