SUMMARY
Over the past 20 years, vehicle operating temperatures have increased by approximately 20-40 degrees Fahrenheit to enhance fuel injection system efficiency. This rise in temperature raises concerns about the structural integrity of engine block materials such as steel, cast iron, and aluminum. The ideal operating temperature for these metals, particularly regarding their ability to withstand pressure (psi), remains a critical question. While thermostat settings have fluctuated from 180 to 190+ degrees Fahrenheit, recent trends have reverted to 180 degrees due to the high temperatures generated by catalytic converters.
