how to read water temp gauge

The water temperature ranges from C to H, where C represents 60 degrees. As long as the pointer on the water temperature gauge reaches C, it indicates that the water temperature has reached 60 degrees; The temperature represented by the H red grid is 110 degrees, and the approximate temperature indicated by the water temperature gauge can be estimated from a span of 60 to 110 degrees. It is advisable to always keep the pointer in the middle position. When the pointer enters the red area, it indicates that there is a problem with the heat dissipation of the car engine. If you continue to drive forward at this time, it is likely to burn out the car engine. That is to say, if the engine coolant boils, it will cause the water tank to expand and crack, and the engine will overheat and be damaged. The direct cause is poor engine heat dissipation. For example, small displacement cars climb mountains with air conditioning in summer, increasing engine load. Long term use of vehicles without cleaning the dirt inside and outside the water tank can affect the circulation and heat dissipation of the cooling water in the water tank. Damaged fans or other heat dissipation components, inability to assist the water tank in heat dissipation in a timely manner, etc., can all cause the cooling water in the water tank to reach its boiling point.

The water temperature gauge of a car depends on the temperature, which should be within a certain range. The normal temperature is when the pointer points to the center at 90 degrees. After the car starts, the temperature of the antifreeze will also rise, and the pointer will reach the center position. The heat exchange is balanced, and the temperature of the antifreeze will not rise again. Therefore, in general, reaching the center position is the best starting point.

The indicators of the water temperature gauge on the Dashboard panel are different, but the criteria for judging the water temperature are the same. The general indication is in the middle position, around 90 ℃ is appropriate. The engine coolant temperature is not as low as possible, nor is it as high as possible. Within a certain range, the normal temperature is 90 ℃ at the center of the pointer. After the vehicle starts, the temperature of the antifreeze rapidly increases. After the pointer reaches the central position, the temperature of the antifreeze in the heat exchange balance no longer rises. Generally speaking, the best start is when the temperature reaches the middle position.
