In summer it is common to see the water tank of cars boiling due to the hot weather, so that it is quite necessary for drivers to conduct precautious examinations on cars to prevent from such accidents. What is more, constant check on the condition of cars is also helpful.

First, it is quite necessary for drivers to know the reasons for the boiling of water tank of cars. The lack of cooling water in the water tank also result in the boiling of water tank of cars. In addition, there is always something wrong with the thermostat, the auto radiator and the electronic fan, which also lead to the problem. When the water in the water tank reaches its boiling point, water vapor comes out from the hood of the engine. When drivers come across such problem, they have to get off the cars to make sound repair.

Next, drivers should notice that their good habits could help them get rid of such problem. For example, they had better conduct regular examination on the water tanks of their cars. Before they start to examine the water tanks, it is also important for them to make sure that other parts of the cars are of normal condition. Only when the fuel and oil are under normal condition and when the spark plugs and antifreeze are well could drivers start the examination of the water tanks.

Under normal condition, the temperature of the upper part of the water tank should be consistent with that of the lower part of the water tank. If the temperatures are not coordinated with each other, namely one side of the water tank is cooler and the other side of it is warmer, we can conclude that there is something wrong with the water tank and something may have blocked the inner part of it. In order to deal with the problem, we could make use of some cleaning agents to remove the dirt of the water tank.

In general, drivers should not make the engine of cars overloaded with heavy burden, especially when it is initiated. Besides, it is drivers' obligation to maintain a cleaning condition of the internal part and external part of the cooling system of cars in order to better serve for the auto radiator. Timely cleaning on the auto radiator is also crucial for sound prevention against water tank boiling of cars.
