Can the car engine compartment be washed with water?

It is possible to wash the car engine compartment with water, but there are five situations where water should not be used to rinse the engine compartment: 1. When the engine is hot; 2. Electrical connectors that have not been waterproofed; 3. Aftermarket headlight assemblies that have been replaced; 4. Spark plugs must absolutely not come into contact with water; 5. The fuses inside the car should not get wet, as directly rinsing with water can easily cause a short circuit, leading to circuit damage. Common car engine compartments are located at the front of the vehicle, while some sports cars use mid-rear or rear-mounted engines, so the engine compartments of these sports cars are at the rear of the car. The engine compartment hoods of cars can be opened to facilitate engine maintenance.
It's best not to wash the car engine compartment with water, as I've seen many troubles caused by such incorrect operations over years of repairing cars. The engine compartment contains many delicate electronic components, such as wire connectors and computer sensors, which can short-circuit or corrode if water gets in. Also, wet battery terminals can cause sparks, which is very dangerous. I recommend waiting until the engine cools to room temperature, then spraying a specialized engine cleaner, scrubbing, and using a low-pressure air gun to blow away dust. If you really want to use water, avoid the wiring and air filter area, and never use a high-pressure washer. After cleaning, make sure to check every corner for dryness, otherwise, the engine might not start or could emit smoke, leading to trouble. Regular cleaning can reduce oil buildup and prevent overheating, but it must be done carefully and cautiously.
