How can the car stop and hear the purring sound of the water tank?

After parking, the auxiliary water tank grunted, but the water temperature was not high, so it was not a cylinder pad.

There are many reasons that cause the engine water temperature to be too high or even "boiling", such as the damage of electronic components (thermostat, cooling fan) of the cooling system, poor heat dissipation of the radiator, and insufficient coolant.

You can pull over, but you can't turn off the engine immediately, because the coolant temperature is too high and the cooling capacity has reached its limit. If the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft). If it is an electronic water pump engine, the temperature is too high to cool, and the engine will be hard to bear.

Preventive measures:

In fact, the "boiling" of cars can be prevented, even in summer. As long as you pay attention to the maintenance of your car and pay attention to some small details of your car, you can put an end to "boiling" in the bud. ?
