A coolant flush removes old, worn-out antifreeze and refills your system with fresh fluid so your engine stays at the right temperature. Over time coolant breaks down and can let rust and deposits build up, which leads to overheating. This service keeps your cooling system clean and protects against both overheating in summer and freezing in winter.
Find a TechnicianMost manufacturers recommend a coolant flush every 30,000 to 60,000 miles, or every few years. Your owner's manual will give the exact interval for your car and coolant type.
Topping off helps in a pinch, but it doesn't remove the old, broken-down fluid or any rust and deposits inside the system. A full flush restores proper protection and keeps the cooling system clean.
Old coolant loses its anti-corrosion protection, letting rust and sludge clog the radiator and water pump. That can lead to overheating and costly repairs, so a flush is cheap insurance.
