A control valve for a heat exchanger adapted to temper the temperature of a first fluid by heat exchange with a second fluid. The control valve includes a housing adapted to fasten adjacent a wall of the heat exchanger, with the housing defining a chamber separate from a compartment. When fastened to the heat exchanger, the housing communicates the compartment with the flow channels of the second fluid, and opens the chamber to flow of the first fluid via a passage through the adjacent wall of the heat exchanger. A valve member is in the compartment for selectively controlling communication of the compartment with a source of the second fluid, and a thermostat is positioned in the chamber to contact the flow of the first fluid, with the thermostat controlling the valve member responsive to the temperature of the first fluid.
