Does the engine compartment need regular cleaning?
2 Answers
The engine compartment does not require regular cleaning because the exposed parts of the engine are not affected by dust, and the areas susceptible to dust are already well-protected. However, frequent cleaning of the engine compartment can lead to problems. Common issues include the following faults: Electrical faults: The engine is the core component of a car, filled with sensors and wiring harness connectors. If water accidentally enters during cleaning, it can easily cause a short circuit, leading to blown fuses or damage to the engine's computer, which can have serious consequences. If the computer module gets wet, it can cause faults in other areas. Engine rust: The engine is generally positioned low, and water may not drain properly when washing the compartment. Normally, the water would evaporate when the engine starts, but if moisture is not promptly removed, it can cause localized rust, affecting the lifespan of the components. Headlight faults: Headlights are not completely sealed. During operation, ventilation holes on the headlight housing maintain pressure balance inside and outside. If cleaning is not done carefully, it can cause fogging inside the headlights.
With over 20 years of driving experience, I can confidently say that the engine compartment must be cleaned regularly. Dirt such as oil sludge and dust not only accelerates metal corrosion, leading to oil leaks or electrical short circuits, but can also clog the radiator fins, causing the engine to overheat and fail. I remember once neglecting the cleaning, and it ended up costing me nearly ten thousand yuan in parts replacement. Professional cleaning uses chemical cleaners instead of high-pressure water guns to protect electronic components. I recommend doing it every six months, or quarterly in dusty or rainy areas. After cleaning, the engine runs much quieter, its lifespan extends by at least two to three years, and most importantly, potential issues can be detected early to avoid breakdowns on the road. In short, putting in a little effort to maintain cleanliness brings huge returns by preventing major troubles.
