We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

Both are common, and the right choice depends on budget and destination: 1. Container shipping (20ft/40ft): The car is sealed inside a container, offering better protection and allowing you to load spare parts inside the car. Typical cost from Shanghai to major world ports: $1,500-$3,000 per car. Best for long distances and high-value vehicles. 2. RoRo (roll-on/roll-off): The car is driven onto the ship and secured on deck. Cheaper ($800-$1,800 to most ports) and faster to load, but exposed to weather and port handling. Not all routes offer RoRo service. Transit time examples: to the Gulf 15-25 days, to West Africa 30-45 days, to Latin America 25-40 days, to Europe 20-35 days. Ask your exporter which option serves your destination port, and always insure the shipment for full value.

Mainstream Chinese automakers rarely publish official English versions of their underlying circuit diagrams. We can provide some models' original Chinese technical documents (PDF) for B2B clients, which you will need to translate for your local mechanics using translation software.
