ABSTRACT:
A process for reducing the pressure buildup in an automobile radiator which contains a bottom section, a radiator header, a multiplicity of tubes extending between the bottom section and the radiator header, and a heat expansion chamber disposed at least about 0.5 inches above the radiator header and connected to the radiator header by a conduit. In this process, hot fluid containing antifreeze at a temperature of at least about 200 degrees Fahrenheit is flowed through the radiator tube; but hot fluid flow into the heat expansion chamber is prevented. The heat expansion chamber is made from a material with a resistivity at 20 degrees Centigrade greater than about 6 microhoms-centimeters; and the material within the heat expansion chamber has a resistivity at 20 degrees Centigrade of from about 6 to about 40 microhms-centimeters.
