How High Water Level Can Cause Engine Water Intake?

[StellaRose]

For ordinary sedans, when the water level reaches above 20 centimeters (for SUVs with higher chassis, this value increases to 30 centimeters), there is a risk of engine water intake. Additional information is as follows: 1. Ways of engine water intake: There are mainly two ways for engine water intake: first, due to the low position of the engine intake pipe entrance, rainwater is sucked into the engine when the vehicle wades through water; second, because the exhaust pipe outlet is below the water level, rainwater is sucked into the engine from the exhaust outlet when the vehicle wades through water. 2. Consequences: After the engine takes in water, it will inevitably stall. Since the rainwater entering the cylinder has no lubricating effect, blindly restarting the engine after stalling may cause the engine to be scrapped due to cylinder scoring.
