What are the consequences of an engine shutting down automatically due to lack of water?

[Zoey]

Running a car without water in the radiator can cause the engine to overheat and damage its internal components. Here is a detailed explanation: 1. No water in the radiator: Running out of water in the radiator is very serious. Lack of water in the car's radiator can cause the engine to overheat, damaging its internal parts and even leading to complete engine failure. If the car's radiator is out of water, you must stop driving immediately. Continuing to drive without water in the radiator will cause the engine temperature to rise excessively, preventing normal oil film formation between parts. In mild cases, this can cause cylinder scuffing or bearing damage, while severe cases can result in total engine failure or even complete destruction. 2. Cylinder: The temperature inside the cylinder will rise rapidly. If the excess heat is not dissipated promptly and high-load driving continues, the strength of components such as pistons, piston rings, and connecting rods will decrease, potentially leading to deformation. These parts may no longer withstand normal loads, and the normal gaps between components will be disrupted, preventing proper oil film formation. Mild cases can cause cylinder scuffing or bearing damage, while severe cases can lead to complete engine failure or destruction.
