The world car industry is in an era of internal combustion engines in the past 100 years of environmental, energy and IT is eco-friendly, high-tech cars technologies are bringing an era of change. Until now, the study of new technologies in automobile research and development has been focused on. The car's new technology development is also important, but it's cutting-edge technology is used in the car before the car's performance, and became an important point in the customer experience improvement problems. New technology development, as well as effective for existing technology applied is also important. This study was to determine the effects of temperature and the performance of automobile engine and determine the cause of the content in accordance with the type(tap water, distilled water, underground water) of anti-freeze and water that is contained in the automotive engine cooling water for the effective application of the anti-freeze. In the freezing point of the coolant -10, -20, -30, -40, $-50^{\circ}C$ dynamo performance test was conducted with the numerical analysis. Water (distilled water) were measured at the reference point peak performance 71.112, 99.622hp freezing $-10^{\circ}C$.
