When the engine works, the temperature of gas in the cylinder can reach 1727-2527 ℃, if the gas is not cooled in time, the temperature of parts of the engine is too high, and particularly parts directly contacted with high-temperature gas influence normal fit clearance due to thermal expansion, so that moving parts are blocked or even blocked. In addition, the high temperature causes a decrease in mechanical strength of engine parts, rendering the lubricating oil useless, and the like.

Therefore, cooling of the engine is particularly important. The radiator water tank is an important part of the engine, the air tightness of the radiator water tank directly influences the working efficiency of the whole engine, the radiator water tank is connected with a cooling chamber of a combustion chamber of the engine, partial heat absorbed by heated parts can be timely dissipated, and the engine is guaranteed to work in an optimum temperature state.

When the engine works, the cooling liquid flows in the radiator core, the air passes outside the radiator core, the hot cooling liquid is cooled due to the heat dissipation to the air, but the radiator is also provided with an important small part, namely a radiator cover, and the small part is easy to ignore. Along with the temperature change, the cooling liquid can expand with heat and contract with cold, the internal pressure of the radiator is increased due to the expansion of the cooling liquid, when the internal pressure reaches a certain value, the radiator cover is opened, and the cooling liquid flows to the liquid storage tank; when the temperature is reduced, the cooling liquid flows back to the radiator, and if the cooling liquid in the liquid storage tank is not reduced and the liquid level of the radiator is reduced, the radiator cover fails.
