What is the cause of the explosion of the car water tank?

1. No antifreeze was added in winter. Cold water will crack when it freezes, because the material of small water tank is not as good as that of main water tank. 2. If the water tank is not cleaned or changed for a long time, it will slowly corrode and perforate under the pressure of water pound circulation. 3. The cylinder gasket of the engine leaks a little, and then the gas rushes into the water tank, and the inferior material is broken first under the huge air pressure.

Water tank plays an important role in the cooling and heat dissipation of automobile. Causes of explosion of automobile water tank;

First, the water tank is in a high-pressure sealed state, and the water in the car has just been opened for a long time, and it is already in a high temperature state or even in the form of gas. Just like a high-pressure boiler, welding makes the water tank leak, and the gas in the water tank can't be discharged at once, leading to an explosion;

Second, there are flammable and explosive substances in the water tank. For example, some inferior antifreeze is used to produce explosive substances, or the water tank is too dirty to produce biogas and other substances, or there is fuel in the water tank, and welding is just a fuse.
