on dash water temp gauge -in dash

• 2023-04-20

The water temp gauge on dash of a car varies, but the criteria for determining water temperature are the same. Generally, the indication should be in the middle position, around 90 ℃. The engine coolant temperature is not as low as possible, nor is it as high as possible. It should be within a certain range, and the normal temperature is 90 ℃ in the center of the pointer. 

On dash of a car, there is a thermometer with two corrugated markings below it, which is called a water temp gaug light, commonly known as a water temperature gauge. The engine water temp gaug light is used to indicate the temperature of the engine coolant. Normally, when the car key door is opened, the car self check light will turn off after a few seconds. 

If the water temp gauge light remains on, it indicates that the engine coolant temperature is too high or the engine is lacking coolant. It is possible that there is a leakage point in the engine cooling system, such as water pump leakage, pipeline damage, water tank damage, etc.

After pulling the cylinder, it is necessary to replace the cylinder liner. There are many reasons for the high engine water temperature, such as too much dirt on the surface of the radiator tank, damaged electronic fans behind the radiator tank, and prolonged non replacement of the coolant. 

The engine of a car is water-cooled, which relies on the continuous circulation of coolant within the engine for heat dissipation. There are two circulation paths for coolant in the engine, one is systemic circulation, and the other is small circulation. When the engine is first started, the coolant will undergo a small cycle, and at this time, the coolant will not pass through the radiator to dissipate heat, which is beneficial for the engine to quickly warm up.After the engine reaches normal operating temperature, the coolant will pass through the radiator to dissipate heat, which can keep the engine within the normal operating temperature range. Long term use of coolant can lead to an increase in freezing point and a decrease in boiling point, so the coolant needs to be replaced regularly. If not replaced for a long time, it will affect the normal operation of the engine. When replacing the coolant, be sure to drain the old coolant from the cooling system thoroughly.
