How High Water Level Affects Vehicles

[SanJessica]

Theoretically, as long as water does not submerge the air intake, it won't affect the engine. However, there are too many unpredictable factors. When other vehicles pass by, waves may splash into the air intake. Additionally, it's crucial to pass through slowly since underwater conditions are unknown. Also, be mindful of stalling while wading through water and never attempt to restart the engine immediately. Below are relevant details: 1. Exhaust pipe height: This represents the safe wading depth. In fact, the pressure generated by engine exhaust is substantial enough to expel water that backflows into the exhaust pipe. Maintaining sufficient and stable power can prevent water from entering the exhaust pipe, ensuring safe passage through waterlogged sections. 2. Half-wheel height: This may lead to water entering the vehicle interior. Modern cars are equipped with numerous electronic components and sensors, making water infiltration particularly troublesome. 3. Air intake height: This is the maximum wading limit. The air intake height is the most critical indicator for vehicle wading depth because once water enters the intake, it can cause engine stalling. In severe cases, water may be sucked into the engine, resulting in permanent damage.
