What is the symbol of an automobile water tank?

The symbol of an automobile water tank is the engine oil pressure alarm light, which serves as a warning. If it keeps on or flashes during the normal driving of a vehicle, it means the engine may be short of oil, which is a serious problem that may cause severe damage to the engine.

The reasons for the constant or flashing of the engine oil pressure warning light are:

1. The engine lacks oil, leading to a lack of lubrication system or insufficient oil, resulting in low oil pressure. The solution is to add engine oil.

2. The oil is too dirty or viscous, causing the oil pump to be unable to effectively suck and pump the oil, leading to low or no oil pressure. The solution is to replace the engine oil.

3. The oil is too thin or due to high engine temperature, the oil becomes thin and leaks from the various friction gaps of the engine, leading to low or no oil pressure. The solution is to change the oil or repair the cooling system.

4. The oil pipe leaks oil, the oil pump is damaged or its parts are worn out, leading to a decrease in the oil intake and output, or even no oil pressure at all. The solution is to check the engine.

5. The gap between the crankshaft and the large and small end covers is too large, causing oil to leak and leading to low oil pressure. The solution is to check the engine crankshaft.

6. The spring of the limiting pressure or relief valve is too soft, the valve is stuck or the steel ball is damaged, leading to the loss of the function or weakening of the valve, resulting in low oil pressure. The solution is to replace the limiting pressure or relief valve spring.

7. The oil pressure sensor or gauge is broken or the circuit is faulty, leading to low oil pressure. The solution is to replace the oil pressure sensor or gauge.

In summary, the symbol of an automobile water tank is the engine oil pressure alarm light, and its constant or flashing indicates a serious problem that may cause damage to the engine. The reasons for the warning light to keep on or flash are various, such as low oil pressure, dirty or viscous oil, thin or leaked oil, oil pump damage, and so on. The solutions are to add or replace engine oil, check the engine, or repair the cooling system or oil pressure sensor.
