What are the symptoms of water entering the engine?

[TimothyFitz]

Engine water ingress is generally divided into three scenarios. The first is engine submersion, which does not damage critical components; the second is slight water ingress, where the engine can still start normally. The third is when a large amount of water enters the engine cylinders, preventing normal engine startup. Below is a partial introduction to the three symptoms of engine water ingress: 1. Engine submersion: If you promptly call for a tow truck to take it to a repair shop and clean it properly, there should be no major issues. 2. Slight water ingress: This situation is the most dangerous because the vehicle can still start normally, and many people unknowingly continue to drive, leading to major engine repairs or total failure. 3. A large amount of water entering the engine cylinders: In this case, the engine cylinders are filled with a significant amount of water, the crankshaft cannot rotate, and the starter does not work. Immediate cleaning is required.
