Should the car engine compartment be cleaned?

[NoahDella]

Engine compartment needs cleaning, here is the relevant information: 1. In fact, engine compartment maintenance is more important than exterior car washing, because accumulated dirt in the engine compartment will affect driving safety as the vehicle ages. Therefore, the cleanliness of the engine compartment also determines the safety level of the vehicle. 2. Dirt covering the engine surface will affect heat dissipation, leading to excessive engine compartment temperature. This not only impacts engine lifespan but also accelerates aging of internal components like wiring harnesses, creating safety hazards. 3. During vehicle use, an oily sludge forms on the engine surface, which significantly increases the probability of engine spontaneous combustion. It also makes it harder to detect surface issues with wiring harnesses.
