The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.

If the original owner included the factory slow charger, we will package and ship it together; if it's lost, the platform does not provide it. Note that the factory plug is a Chinese three-prong socket, and an adapter is needed overseas.

A Chinese VIN is 17 characters, and decoding it takes minutes but reveals a lot. Positions 1-3 are the World Manufacturer Identifier. Cars sold domestically in China usually start with L (for example LFV for FAW-VW, LGB for Dongfeng Nissan), which tells you it was built in China rather than imported. Position 10 is the model year letter or number. Positions 4-8 describe the model, body type, and drivetrain, so you can verify the seller's description matches the actual car. Cross-check the VIN in three places: the plate at the base of the windshield, the sticker on the door jamb or B-pillar, and the registration certificate. Mismatched VINs or signs the plates were re-riveted are a serious red flag for a cloned or rebuilt vehicle. Use the VIN to pull a history report from a Chinese data provider and to verify recall status with the manufacturer. Any seller who hesitates to share the full VIN is telling you something important.
