The exclamation point marked red in the middle of the water temperature gauge and the oil temperature gauge indicates that it has reached a certain level, and there will be a certain danger if it is straightened beyond this level.

The temperature of the engine is usually sensed by the water and oil temperature sensor, so it is often connected with the normal temperature of the engine and the water and oil temperature. Generally, the engine water temperature is the best of 90 °, but the temperature of the engine varies under different working conditions. It may be about 85 ° C in the cold state, and the water temperature can reach more than 100 ° C in the hot state. However, some people often regard 90 ° C as the normal water temperature of the engine, which will float up and down at 90 ° C in actual driving.

Several common reasons for high water or oil temperature in cars:

1. Insufficient coolant, coolant leakage or lack of coolant will cause the engine water temperature to rise. At this time, you should check the coolant condition. If it is insufficient, first add it to the appropriate position, and then check whether the liquid level drops seriously in a few days. If so, find the leakage position.

2. If the cooling fan fails, when the vehicle is running at high speed, the heat generated cannot be transferred to the antifreeze in time, which will affect the heat dissipation, and then cause the antifreeze temperature to rise, resulting in problems such as boiling.

3. Circulating water pump failure water pump failure includes bearing locking and impeller damage. Bearing locking is rare. Impeller damage usually includes impeller cracking or impeller loosening from the pump shaft, which leads to slow coolant circulation speed and easy to cause engine temperature to be too high.

It is worth mentioning that the engine water temperature is not as low as possible. Low water temperature will also cause insufficient combustion of engine mixture, reduced power, poor lubrication and excessive emissions
