A heat exchanger, in the form of a radiator, for the coolant circuit of an internal combustion engine. The radiator has an upper water tank, a lower water tank that is connected to a return line, and heat exchanger tubes that extend between the upper and lower water tanks. For more uniform thermal transmission, an air-withdrawal line extends through the heat exchanger register and the lower water tank into the return line.
