What components must be replaced in a flood-damaged vehicle?

[Violet]

All electrical equipment basically requires inspection, repair, or replacement. The following components need to be checked: 1. Headlights: If the vehicle was submerged deep enough to cover the front end, the headlights have likely been damaged. After water exposure, a layer of white fog (condensation) may appear inside the headlights, significantly affecting their performance. 2. Chassis: The vehicle chassis is typically one of the most severely damaged components after water exposure, as inspection underneath the vehicle is difficult. Various debris such as plastic bags often adhere to the underside of the chassis and may stick to the exhaust pipe. 3. Air filter: As everyone should know, the air filter functions like the engine's lungs, filtering impurities from the air. If airborne contaminants enter the cylinders, they will cause severe wear to the cylinder walls during engine operation.
