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.

No, it does not. International shipping (especially RoRo) usually takes 30 to 60 days, during which the vehicle is stationary. A dead 12V battery, natural tire pressure loss, and even wiper aging due to temperature differences are all reasonable physical wear during long-distance transport. We strongly recommend that overseas buyers bring a portable jump starter and an air pump when picking up their vehicles at the port.

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.
