What are the priority inspections for a new car upon arrival by sea

Export heavy trucks may experience slight changes in their condition after prolonged sea transportation, salt spray erosion, cabin turbulence, and fixed pulling. Many overseas customers directly put their cars into operation after picking them up, ignoring the landing inspection, resulting in hidden sea damage evolving into oil leakage, circuit failure, paint rust, abnormal braking, and other problems, affecting the attendance rate of new cars. After the new car arrives at the port and lands, the principle of first inspection, then commissioning, and then operation shall be followed, and several core inspections shall be focused on, which can effectively avoid later failures and ensure the long-term stable use of the vehicle.
Prioritize checking the overall appearance and paint sheet metal condition of the vehicle. Sea salt spray can easily cause paint loss, floating rust, white spot corrosion, and may also cause scratches and bumps when fixing or moving the cabin. The first thing to do upon landing is to conduct a full vehicle inspection, with a focus on inspecting unprotected areas such as the corners of the frame, chassis sheet metal, and carriage welds, to confirm if there are any paint peeling, scratches, or rusting issues. If any damage is found on the paint surface, it should be repaired in a timely manner to prevent rust and prevent salt spray residue from continuing to corrode the steel plate.
Focus on inspecting the chassis fastening and suspension system. Ship navigation is subject to significant turbulence and vibration, which can easily cause loosening of chassis screws, displacement of bushings, and increased clearance between supports. It is necessary to conduct a comprehensive inspection of the fastening of the main beam bracket, steel plate spring, lifting ear, U-bolt, and balance shaft, and re tighten the loose parts with standard torque. At the same time, check the chassis for deformation, misalignment, and cracking, and eliminate potential hazards during heavy-duty driving in advance.
Check for leaks in the piping, valve body, and sealing system. Shipping shaking can cause slight loosening of oil and gas pipe joints, displacement of valve body seals under pressure, and potential micro leakage hazards. It is necessary to inspect the hydraulic pipeline, brake pipeline, accumulator joint, and valve interface one by one, and check for oil and air pressure leakage. At the same time, clean up the accumulated water and salt on the chassis to prevent long-term corrosion of the interface from causing later air and oil leaks.
Verify the electrical system and all vehicle lighting. A high humidity salt spray environment can easily cause oxidation of plugs, moisture in circuits, and abnormal sensor signals. After landing, prioritize power on for self inspection, check the status of the dashboard malfunction lights, and test the high and low beams, turn signals, brake lights, and reverse lights of the entire vehicle. Check whether various chassis plugs, ABS connectors, and wire harness sheaths are intact, remove the oxide layer on the plugs, and ensure stable operation of the electrical system.
Check the tires, wheels, and parking status. Tightening during sea transportation can cause long-term stress on the tires and tight parking brakes. It is necessary to check whether the tire pressure is abnormal, whether there are compression cracks on the tire surface, and whether the wheel hub is corroded or bumped. At the same time, test whether the parking brake and brake pedal travel are normal to avoid driving with faults.
Overall, the core of the new car landing inspection revolves around exterior rust prevention, chassis fastening, pipeline sealing, electrical self inspection, and verification of the walking system. Conducting standardized re inspection after sea freight can help identify hidden damages in advance, enabling new cars to be put into operation in their best condition and significantly reducing overseas new car failure rates and after-sales costs.
