Chevy radiators were among the first in history to transform the process of heat-dissipation. In the early days of auto-manufacturing, radiators consisted merely of round tubes through which water flowed in order to carry heat away from burning engines. General Motors, however, realized that redesigning these tubes to be more elliptical than round was a smart way to improve their efficiency.

With more efficient radiators came more hotly burning engines. In principle, there were few limits to the power that the combustion process could generate. Practically speaking, however, engines could not hit temperatures so hot that they threatened to melt themselves as well as all their surrounding parts, which is why so much attention came to be placed on dissipation in the early days of the auto industry.

Modern-Day Chevy Radiators

Today, Chevy radiators, like those of other manufacturers, have added literally dozens of technological innovations to help maximize cooling capabilities. These include the use of fans to generate a constant air current over the radiator's "fins," antifreeze to protect engines from crystalizing in the dead of winter, and lighter construction materials such as plastic to reduce the overall weight of engines. The more effective these designs have become at clearing heat from the system, the more room engineers have found to build heftier engines.

Nowadays, whether you drive a more "practical" Chevy such as a Cavalier or Impala, or you drive a "sportier" model such as a Firebird or Corvette, the odds are that your radiator is made from aluminum. While aluminum isn't the ideal material for conducting heat, it does represent the best mix of conduction, lightness, and corrosion-resistance. No matter how technology changes in the coming years, it's likely that aluminum radiators will remain a fixture, both in Chevys and non-GM cars.
