The condenser is located in front of the radiator.

The condenser is made up of aluminum tubing and aluminum cooling fins, which allows rapid heat transfer for the refrigerant. Compressed refrigerant enters the condenser in a high pressure, high temperature vapor state. As the refrigerant flows through the condenser, the heat of the refrigerant is transferred to the ambient air passing through the condenser. Cooling the refrigerant causes the refrigerant to condense and change from a vapor to a liquid. Refrigerant exiting the condenser is in a high-pressure, medium temperature liquid state.
