electric water temp gauge wiring

About the electric water temp gauge , it has three lines , the main line and the auxiliary line , and a signal line . The signal line controls the grounding wire. After connecting the power supply line of the electric water temp gauge , the signal line and the grounding meter will rise . Then connect the water temperature sensor . The automobile water temperature sensor is installed on the water jacket of the engine cylinder block or cylinder head and directly contacts with the coolant .

If you buy an electric water temp gauge with constant sensing (it is required that the screw port of the sensing plug be consistent with that of the car) , install it directly , and fix the gauge on the workbench. It does not need electricity , and it has nothing to do with the key switch . Remove the instrument and replace it with a good water temperature gauge. Buy an inductive water temperature gauge , connect the water temperature sensing plug - switching power supply - instrument , and fix it . Just leave it alone and check regularly to ensure that there is no shortage of water . Santana is short of water (antifreeze) and the water temperature is too high. Don't drive when the light is on !

The electric water temp gauge of the car is used to indicate the temperature of the engine cooling water . When the cold car starts , the water temperature is low , and then slowly rises . Generally, the vehicle will automatically control its temperature to make it reach equilibrium when it is heated to about 90 ℃ . At this time , the working efficiency of the engine is the highest . If you find that the water temperature is higher than the scale you usually see, you should suspect your cooling system . If it is close to the right side of the meter head, you should stop immediately , at least wait until it gets cold before driving, and get out of trouble as soon as possible . Of course , the water temperature gauge refers to the water temperature , indicating the temperature of the coolant. It also indicates the temperature of your engine . The coolant is used to cool the engine , so if the water temperature is too high, the engine will not work properly .
