Why You Should Flush Your Car Coolant System Flushing your car's coolant system is crucial for engine health. Over time, coolant gets contaminated and loses effectiveness. This can lead to overheating and engine damage. A coolant flush removes old fluid and replaces it with fresh coolant. This ensures optimal performance and corrosion protection. Signs your car needs a coolant flush include engine overheating, rusty or discolored coolant, and a sweet smell from the engine.
