Can You Wash the Inside of a Car Hood with Water?

[VanTalia]

You should not wash the inside of a car hood with water for the following reasons: 1. It can easily damage the generator, potentially causing it to fail. 2. If the engine is hot, the sudden temperature change from cold water can cause significant damage. The engine block may crack due to thermal shock. 3. The engine compartment contains many electrical wires, which can be damaged by water and may accelerate aging. Precautions for using water to clean the engine compartment: 1. Cover the generator, distributor, brake fluid reservoir, etc., with a cloth or plastic bag. 2. Try to wash the engine after it has cooled down, and avoid using high-pressure water jets. 3. After washing, thoroughly dry the engine compartment with a clean cloth, especially the underside of the hood. 4. Do not aim the water jet directly at the air intake or electrical connectors.
