Can the car engine compartment be cleaned?

[Lena]

Car engine compartments can be cleaned with a high-pressure air gun, but it is not recommended to rinse directly with water, especially with a high-pressure water gun. Although the electronic components inside the engine compartment are waterproofed, prolonged use may cause the waterproof structure to deteriorate due to high temperatures, reducing its waterproof performance. When cleaning the engine compartment, first ensure the engine is turned off and all electrical components are not operating. Cleaning should be done after the engine compartment has cooled down, avoiding cleaning under high-temperature conditions. This prevents damage to the engine and avoids burns from excessive heat. A thorough cleaning of the engine compartment, especially the engine surface, wiring surfaces, and plastic or rubber parts, can help the engine dissipate heat quickly and protect the wiring inside the engine compartment.
