Liquid Aluminum

Not long ago, coolant leaks required immediate repair. But these days, leaks may go unnoticed until the vehicle starts to seriously overheat. To better meet these evolving challenges, Bar's Leaks® has reformulated its popular Liquid Aluminum™ Radiator Stop Leak into a next-generation stop leak for the entire cooling system. New Bar's Leaks Liquid Aluminum Cooling System/Radiator Stop Leak (p/n 1186) has been specifically formulated to permanently seal the coolant leaks that cause most overheating problems. It now features the proprietary wetting agent Xtreme Cool®. Xtreme Cool reduces the surface tension of coolant - which increases its wetting ability - as well as improves heat transfer and reduces coolant temperature.
