Can You Wash Inside the Car Hood with Water?

[JosephineLynn]

You can wash inside the car hood with water, but the following points should be noted: 1. The exterior of the engine can be washed, but it should be done when the engine is cool. If the engine is too hot, sudden contact with cold water can easily cause the cylinder block to deform or even crack, and the large amount of steam generated can make the engine compartment too damp, affecting some electrical components. 2. Although the engine, fuse box, and wiring are waterproof, avoid using a high-pressure water jet for prolonged washing. While they can handle rain, high-pressure water jets exert too much force. Try to avoid the engine control unit (ECU) and external fuse box areas. 3. For cars older than three years, when washing the engine, wrap the wiring harness and internal fuse box with shrink film, as most plastic structures begin to age and their waterproofing ability declines. 4. Do not wash the engine with water too frequently, as this can accelerate wiring aging. 5. The fuses inside the car must not get wet. Direct water exposure can easily cause a short circuit, leading to electrical burns. When cleaning the engine compartment, try to prevent direct water contact with the fuse box.
