Can You Wash the Engine with Water When Cleaning the Car?

[JudeLynn]

You should not wash the engine with water when cleaning the car. Here are some explanations: Harm to the car: Once the engine gets wet, if not dried in time, it can cause short circuits or open circuits in various components, or damage them, severely affecting the engine's functionality. Inside the engine, components such as the engine control unit (ECU), transmission control unit (TCU), ignition control unit, and various sensors and actuators are installed. Additionally, directly rinsing the engine compartment with water can lead to water residue inside, causing oxidation of electrical connectors, resulting in poor contact, or rusting of fastening screws. Cleaning the fuse box: There is a warning on the fuse box indicating that it should not be washed with a high-pressure water gun. The waterproof function of the fuse box is generally sufficient to handle rain. It is best to clean the car's fuse box with a damp cloth. Avoid using a water gun directly for cleaning.
