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

[IsabelleDella]

You should not wash the engine with water when cleaning the car. Here are some explanations: 1. 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. The engine contains installed components such as the engine computer, transmission computer, ignition computer, various sensors, and actuators. Additionally, directly rinsing the engine compartment with water can easily leave water residue inside, leading to oxidation of electrical connections and poor contact, or rusting of fastening screws. 2. Cleaning the fuse box: The fuse box has a warning 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. Try to avoid using a water gun for direct cleaning.
