Can the Engine Compartment of a Sedan Be Washed with Water?

[Gabrielle]

The engine compartment of a car should not be washed with water, especially using a high-pressure car wash gun, as the high water pressure can potentially loosen some connecting parts or even wash away certain protective measures, posing potential risks. Although the engine compartment is waterproofed, it contains various components, electrical devices, and wiring, so caution is required when cleaning. Precautions for cleaning the engine compartment are as follows: When the car engine is too hot, do not use a water gun for cleaning. If the engine is still hot and comes into contact with cold water, the temperature will drop sharply, potentially causing damage such as cracking or oil leaks. Additionally, steam can affect the vehicle's electrical circuits. Special cleaning agents and tools should be used for engine cleaning. The engine compartment should be cleaned when the car is cold. If the vehicle has just been driven and the engine components have not cooled down to ambient temperature, immediate cleaning may cause damage to the vehicle and could also result in burns during the cleaning process.
