Bar’s Leaks reformulated its popular Liquid Aluminum Radiator Stop Leak to plug leaks in a vehicle's entire cooling system. New Liquid Aluminum Cooling System/Radiator Stop Leak was specifically formulated to permanently seal coolant leaks that cause most overheating problems, the company stated. The sealant is guaranteed by the company to stop leaks in plastic, aluminum and copper/steel radiators, heater cores, gaskets and freeze plugs. It is also compatible with all types of antifreeze, and can be added directly into the vehicle's cooling system with no flushing required, according to the company. Bar’s Leaks Liquid Aluminum is available in case packs of six 16.9-ounce bottles.
