Do not use a high-pressure water gun directly! The high-pressure water can instantly damage the fragile aluminum fins of the condenser, leading to a permanent decrease in cooling efficiency. We can only use a low-pressure air gun or a soft brush for surface cleaning.

Europe and some developed countries have very strict regulations on greenhouse gases. If required by customs, we will specify the exact refrigerant type and charge amount according to the vehicle's air conditioning compressor nameplate in the remarks section of the packing list and commercial invoice.

China has centralized vehicle records you can check remotely before paying anything. Ask the exporter for the 17-digit VIN, then request two reports. First, the maintenance history: third-party platforms pull 4S dealership records showing service dates, mileage and repair items. A mileage line that goes down over time is a red flag for odometer tampering. Second, the insurance claim history: it lists accident dates, claim amounts and repaired parts. Heavy claims involving frame rails or airbags should end the deal. Practical tips: run the reports yourself instead of accepting screenshots from the seller, make sure the report date is close to the delivery date, and cross-check with physical wear such as the steering wheel, pedals and seat bolsters, which cannot lie about high mileage. Keep in mind that small private repairs never enter these databases, so combine history checks with a physical inspection before shipping.
