Which Part of a Car Is Most Dangerous When Water Enters?

[StEliza]

Water entering the car engine is particularly dangerous. Below are relevant details about engine water ingress: 1. Significant water ingress into the engine: If a substantial amount of water enters the engine but does not affect normal driving, though the noise may be louder, it could indicate small amounts of water in the oil or fuel. In this case, changing the oil and cleaning related engine components is necessary. 2. Reasons for a car stalling in water: Water entering the distributor cap can disrupt normal ignition functions, while water in the engine's air filter increases intake resistance and may lead to water entering the combustion chamber, preventing the spark plugs from firing. Restarting the engine under these conditions can easily cause hydrolock.
