As the weather heats up sharply, the first long car starts to boil, and most of the models are on the expressway . No one wants to have a vehicle fault when the speed is 120 km/h . Most drivers think that water temp gauges are unnecessary to install. Some people respond that "the vehicle will alarm if there is a fault, whether or not it is OK" , but the middle and high-end models basically have water temp gauge , so that you can see the basic information of the model , In this episode , we will simply install water temperature gauge .

Water temp gauge set , with instrument, harness, sensor and other accessories . The body of the water temp gauge is self luminous on a white background, which is suitable for observing water temperature at night . The harness of the water temp gauge has 4 wires in total , one of which is a 3-wire instrument. The focus is on the introduction of the 4-wire instrument. The four wires are red (12V open key) , black (ground wire) , blue (signal wire) , and white (power is available when the small light is turned on) . The 3-wire instrument lacks white lighting wires .

Generally, the water temperature fluctuates between 85-100 degrees when the automobile engine is working : 1. The water temperature is from C to H. C means 60 degrees . As long as the pointer of the water temperature gauge points to C, it indicates that the water temperature has reached 60 degrees , and the red grid of H indicates that the temperature is 110 degrees . You can estimate that the temperature displayed on the water thermometer is between 60 and 110 degrees. 2. The water temperature is high when the air conditioner is turned on , because the idle speed of the air conditioner engine will automatically increase , thereby emitting more heat and making your car unable to stop. The cooling speed of the fan is not enough , but this does not happen in ordinary cars , because there is also a temperature controlled fan . 3. Long term high water temperature will reduce the lubricating effect of engine lubricating oil and cause wear of internal parts of the engine . The red wire of the instrument is connected to the positive pole of the battery, and the blue wire is connected to the negative pole of the battery. There is reverse connection protection inside, even if the installation is wrong, there will be no problem.
