What if Chevrolet Lefeng water tank often boils without water?

1. The cooling system leaks, and the water tank and water pipe are only a part of the cooling system. There may be water leakage in other hidden places, such as the small water hole on the water pump, the aging and leakage of the sealing ring in the iron water pipe section, and the leakage of the engine water plug. Don't mislead the fault judgment and waste money and energy because the water leakage in the shelter can't be detected.

If there is no possibility of water leakage, there is only one possibility, that is, the engine is boiling water. Because the engine temperature is too high, the coolant evaporates directly, resulting in a decrease in the amount of coolant. At this time, there will be many phenomena such as high water temperature, engine drilling machine, excessive exhaust emission and white gas emission. To solve this problem, the only way is to disassemble the cylinder head and check the internal situation of the engine (whether it is deformed or worn) before proceeding to the next step (whether it is worn).

Generally speaking, you should pay attention to this problem and not underestimate it. Severe high water temperature will directly lead to engine scrapping. It is recommended to go to a regular enterprise for examination and treatment as soon as possible.
