Can the car hood be opened for washing?
2 Answers
It is not advisable to open the hood to wash the engine, as it may affect the electrical circuits of the engine. Modern engines are closely integrated with electrical systems. It is recommended to use a cloth for wiping when you have time. Moreover, washing with water can accelerate aging and rust in some parts of the engine. For areas that are hard to reach with a cloth, a long-handled cleaning brush can be used. Below are some additional tips for car washing: Pay attention to sealing. Before washing, ensure all doors, windows, engine hood, trunk lid, vents, and air inlets are tightly closed. Seal the engine's electrical system to prevent water ingress during washing, which could cause short circuits, electrical leakage, and rust. When washing a truck, if the cargo is sensitive to moisture, take protective measures or avoid washing the upper part.
With years of hands-on experience in car repair, I generally don't recommend washing the engine compartment under the hood. There are wires, battery terminals, and electronic modules underneath the engine that could short-circuit or corrode when sprayed with water. I once had a friend who used a high-pressure washer, ended up with water in the sensors, and couldn't start the car—costing him hundreds in repairs. The best way to clean under the hood is to wait for the engine to cool, then use a dry cloth or a dedicated engine cleaner to wipe it down. Don't take the easy route and just use water. Regularly checking for dust buildup in the engine compartment also helps prevent issues and prolongs the car's lifespan. Remember, safety first—small mistakes can lead to big troubles. Keeping it clean is important, but use the right tools.
