Can a car engine be washed with water? The precautions are: 1. The engine must be cleaned while it is running; 2. Avoid prolonged washing of any single engine component; 3. Immediately after cleaning, use a high-pressure air gun to dry it thoroughly to prevent water from entering the engine wiring harness connectors, which could cause vehicle malfunctions. An engine is a machine that converts other forms of energy into mechanical energy, suitable for power generation devices. The maintenance methods include: 1. Regularly change the engine oil and oil filter; 2. Keep the crankcase well-ventilated; 3. Periodically clean the fuel system; 4. Regularly clean the radiator; 5. Periodically clean the crankcase.
I've been driving for over a decade. Once, I took a shortcut by rinsing the engine bay with water, and within days it malfunctioned—turns out water had entered the ignition coils, causing a short circuit, and the repair cost me over a thousand yuan. Since then, I only use specialized engine cleaner sprayed on the surface, followed by low-pressure wiping—it's quick and safe. Engine components like wiring, sensors, and batteries are vulnerable to water; contact can easily cause rust or short circuits, and may even spread oil residue, potentially leading to small fires. For regular car washes, it's best to leave it to professionals—don't risk it to save money. Regularly wiping away dust with a cloth is more reliable than rinsing with water and can extend your car's lifespan. Car cleaning involves a lot of know-how—don't underestimate these details.
