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.

A professional pre-shipment inspection typically costs a small fraction of the vehicle price and routinely pays for itself. A thorough inspection covers: paint thickness measurement across 30+ points to map body repairs; structural assessment of pillars, rails and crossmembers for accident damage; engine and transmission operation; a full electronic scan for fault codes; suspension and underbody checks for leaks and rust; and, for EVs, battery SOH and thermal management performance. You receive a written report with photos before the car is loaded — if the car fails, you can stop the shipment or renegotiate. Skipping the inspection to save a small fee is the classic false economy in used car importing: discovering a problem after arrival is far more expensive than preventing it at origin.

If there is a minor leak in the lines due to bumps, it is possible that the cooling may not work upon arrival. This is a normal physical loss. The cost of vacuuming, pressure testing, and recharging refrigerant at a local auto repair shop is low and is the buyer's responsibility.
