1. Hood Screw Identification
To determine whether a used car is an accident vehicle, start by inspecting the front of the vehicle. Open the hood and directly inspect the hood screws—they typically retain their original finish. If the paint on the screws is chipped, scratched, or tampered with, it indicates the hood has likely been disassembled, likely indicating a major engine overhaul. Such a used car is suspected of being an accident vehicle and warrants further inspection.
2. Radiator and Frame Screw Identification
Continue to inspect the used car's radiator frame. The radiator frame can be connected using either welds or screws. If it's a welded connection, there's no need to worry too much. Focus on the screws near the radiator frame and the headlight screws. If these screws show no signs of being twisted or dislodged, it's highly likely the front of the used car hasn't been in a serious collision, and the likelihood of it being in an accident is relatively low. However, be aware that some used cars can loosen related screws when replacing the headlight bulb. Therefore, focus on the radiator frame screws to avoid misjudging the used car's condition.
3. Engine Mount Screw Identification
The engine mount screws are key components that secure the used car's engine to the support beam and are crucial for determining whether the used car has been in an accident. There are three common reasons for removing and installing these screws: First, if a used car has been in a serious accident, the support beam needs to be corrected due to damage and deformation. This situation indicates that the front of the used car is likely severely damaged, typical of an accident vehicle. Second, if the used car's engine malfunctions and requires repair or overhaul, such issues can significantly affect the used car's value. Third, to replace the engine pads. This is routine maintenance for used cars. Engine pads are made of rubber, and replacing them after aging is normal and does not affect the safety of the used car, so there is no need for excessive concern.
