BARS1199 Cooling System Sealer, 11 Oz.

Bar's Leak Cooling System Sealer is a radiator stop leak product designed to seal internal, external, and coolant-to-oil leaks in vehicle cooling systems. This pre-dissolved formula stops leaks in radiators, heater cores, engine blocks, cylinder heads, gaskets, and freeze plugs while protecting against corrosion and mineral buildup that can weaken cooling system components over time.

Bar's Leak seals leaks safely and effectively on plastic, aluminum, and metal radiators. Its water pump lubricant additive reduces wear on the pump seal, helping prevent future leaks before they start. The product works with all antifreeze types and colors, making it a versatile solution for maintaining cooling system integrity across a wide range of vehicles.
