Does the Engine Compartment Get Wet During Car Washing?

Does the engine compartment get wet during car washing? The correct sequence for cleaning the engine compartment: 1. Open the engine compartment for heat dissipation until the surface is not too hot to touch. Do not rinse with cold water when the compartment is at high temperature, as sudden cooling can cause damage; 2. Seal the computer board, air intake, and other parts of the car body that do not require cleaning. Water entering the air intake can prevent the engine from starting, and water on the computer board poses a risk of short-circuiting; 3. Use professional tools such as steam cleaners for cleaning; 4. After cleaning, use an air gun and a towel to dry all parts of the engine compartment; 5. Apply a care solution to the plastic parts of the engine compartment to complete the cleaning.
I've loved cars since childhood and often wash them myself to save money. It's indeed possible for water to enter the engine compartment during washing, such as when using a high-pressure spray around the edges of the engine cover, where water might seep in and cover the battery or sensors. Once during a DIY wash, I accidentally did this and nearly wet the ignition coils, but luckily dried them in time without incident. Modern vehicles are designed with drainage channels and seals to reduce risks, but since the engine bay isn't completely sealed, high-pressure water can force its way in. For safety, it's recommended to use a low-pressure spray or sponge for external cleaning, avoiding direct spray on internal critical components. After washing, remember to wipe exposed areas with a dry cloth or leave the hood open to air dry for a few minutes to prevent water accumulation that could corrode wiring. Regular maintenance also helps—periodically removing dust reduces the chance of moisture absorption. In short, better safe than sorry; learning more protective knowledge helps safeguard your beloved car.
As a car enthusiast who has observed for years, I've noticed that water entering the engine compartment during car washing is not an uncommon issue. The engine bay structure allows for minor water ingress, but high-pressure washing or heavy rain may force excessive water intrusion, potentially causing fuse blowouts or short-circuit risks. Vehicle designs incorporate baffles and drainage holes to handle natural water entry, but human factors like forceful washing can exceed these limits. For instance, direct spraying in the electronic control unit area may trigger fault codes or starting difficulties. I believe the safest approach is to turn off the engine and let it cool for at least 15 minutes before washing, then use low-pressure water flow to gently clean surfaces while avoiding sensitive components. After washing, it's advisable to check for water accumulation and use a blower or cloth to dry damp areas. Understanding differences between vehicle models is also practical - compact cars with weaker seals require extra caution. Overall, prevention is better than repair, and choosing professional car wash services proves more reliable.
