automotive water temp gauge

• 2022-02-25

In addition to the speedometer, voltage and fuel gauge in the automobile instrument panel, there is another meter worthy of our attention. It is the water temp gauge. The water temperature is the engine coolant temperature. Once it is too high or too low, there is a problem. The normal picture of the water temp gauge should be that the pointer does not approach h or the red dangerous area.

No matter how the manufacturer designs, the automobile water temperature gauge is generally marked with the two English letters C and H, or distinguished by white and red areas. If the water temperature gauge approaches h or the red dangerous area, and the water temperature alarm light is on in severe cases, it indicates that the engine coolant is too high.

Still, stop the machine in time to dissipate heat and check whether the machine coolant is normal, If the water temperature ishigh.However, supplement it, If the water temperature is high due to lowercoolant.In addition, I believe everyone knows that high machine water temperature is bad, but you know, low machine water temperature also has disadvantages. Low water temperature will beget inadequate combustion of machine admixture, reduced power, poor lubrication and inordinate emigration.

In order to insure that the machine works within the normal temperature range, the vehicle will be equipped with machine coolant temperature detector, which is generally displayed independently on the vehicle instrument panel (water temperature hand). Still, an alarm will appear, If the antifreeze temperature is too high. Generally speaking, the machine water temperature hand adopts physical or virtual dial pointer display, while a many vehicles have no instrument panel, and the warning sign appears only when the temperature is too high.

The pointer orientation of both physical and virtual water temperature meters is basically similar, which is generally marked with 60 ℃ - 120 ℃ dial or cold (c) - hot (H). Antifreeze is different from traditional tap water. It can work at a temperature above 100 ℃ due to the addition of calcium chloride, methanol, ethanol, ethylene glycol, glycerol and other components in organic matter.The lower the engine coolant temperature is, the better. The higher the engine coolant temperature is, the better. It needs to be within a certain range. The normal temperature is 90 ℃ in the center of the pointer. After the vehicle starts, the antifreeze temperature rises rapidly. After the pointer reaches the central position, the heat exchange balance antifreeze temperature will not rise. Generally speaking, it is best to start when the temperature reaches the middle position, which is one of the reasons why the vehicle needs to be hot before starting.
