The condenser of the air conditioning system is made of aluminum. It condenses the injected refrigerant and discharges the heat into the atmosphere. The condenser is mounted directly in front of the radiator. This location improves its cooling by the counter airflow from the engine cooling system. For a more efficient cooling process of the A/C condenser when the vehicle is at rest, it is equipped with additional electric fans. The condenser is the most vulnerable part of the automotive air conditioner, because it is subjected not only to mechanical damages, but also to electrochemical corrosion. Consequently, from all the elements of the cooling system, the condenser is the first to fail.

Unfortunately, the problem of replacing the condenser radiator occurs quite often. This is due to the fact that it is the first to be attacked by salt particles, dust and small stones. Apart from that, the condenser tubes go out of order quite often because of their construction. They are generally very thin, and this is the main reason for them to be exploited no longer than two years. It is recommendable to replace the A/C condenser when it loses its impermeability due to corrosion.
