After being subjected to high-temperature burning, the plastic insulation layers of various wiring in a fire-damaged vehicle have aged and are prone to causing short circuits. Minor cases may result in blown fuses and damage to electronic control components, while severe cases can lead to spontaneous combustion. Here are specific precautions for inspecting fire-damaged vehicles: 1. The upper part of the engine often has many replaced components, including all wiring harnesses. After replacement, there will be a noticeable contrast between the new and old parts. If you find that a used car has had its engine compartment wiring harness replaced along with numerous plastic components, it is highly suspicious that the vehicle has been fire-damaged. 2. When repairing a fire-damaged hood, usually only the surface is treated. If there is sound insulation material on the inner side, it is generally left untouched. During inspection, pay attention to the interior of the hood. The edge sealant around the hood will have fallen off and must be reapplied. The reapplied sealant will feel significantly different from the original factory sealant, which can serve as one of the reference points. 3. Areas near the fire-damaged spots will show paint cracking, but not all areas will be treated. The fireproof insulation material near the firewall is usually not replaced unless the fire damage is severe, as it is difficult to remove. Therefore, these areas should be closely inspected.
