The engine coolant in your vehicle needs to be flushed regularly because it loses its effectiveness to lubricate the water pump and other important coolant system components. New coolant fluid helps to reduce foam and rust throughout the coolant system. Over time your coolant fluid may not be capable of properly cooling your engine. You will help decrease the need for coolant related repairs and help prevent overheating. It also comes with a BG Lifetime Protection Plan if the service is performed before your vehicle has 75,000 miles. youtu.be/9iF6n-XDHGo
