Should the car engine compartment be cleaned?
2 Answers
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.
Every time I service my car, I check whether the engine bay needs cleaning because excessive dust accumulation can affect cooling performance, leading to component overheating or short circuits. For example, two years ago I neglected this, and dust clogged the air intake, causing a noticeable increase in fuel consumption. When cleaning, using a soft brush and specialized cleaner is safe enough—never use a water jet directly on electronic components, as it can cause rust or malfunctions. Regular wiping can also help detect oil leaks or cracks early, making it quite cost-effective. I recommend a simple cleaning every two to three months, especially for those who frequently drive on highways, as dust builds up much faster. Keeping it clean not only extends the engine's lifespan but also reduces abnormal noises. However, don’t overdo it—excessive cleaning is just a waste of money.
