How Your Radiator Fluid Could Be the Silent Killer of Your Engine
Prevent Costly Engine Failures Before They Strike Your radiator fluid plays a crucial role in keeping your engine cool, but many drivers underestimate its importance—until engine damage occurs. Improper or neglected radiator fluid can lead to serious mechanical failures, wasted fuel, costly repairs, and even dangerous road hazards. In this guide, we’ll uncover how faulty radiator fluid contributes to painful engine failures and share actionable steps to protect your vehicle’s long-term health. ### Why Radiator Fluid Matters More Than You Think Radiator fluid—also known by its technical name, coolant—does more than just regulate engine temperature. It protects critical components from corrosion, bleeding rubber seals, and extreme heat buildup. Properly formulated coolant ensures optimal heat transfer, prevents freezing in cold climates, and maintains system pressure to avoid overheating.
