Does Radiator Fluid Go Bad? Lifespan, Chemistry, and Testing Guide
Yes, radiator fluid (commonly known as antifreeze or coolant) goes bad over time as its critical chemical corrosion inhibitors, rust fighters, and pH buffers deplete and become acidic. While the base liquids-distilled water and ethylene or propylene glycol-do not easily break down, the microscopic additive package eventually exhausts itself from thousands of thermal cycles, leaving […]
