Bar's Leak Original Cooling System Leak Sealant Additive 150 g. Your vehicle's cooling system plays a vital role in its overall performance. Leaking seals and gaskets reduce the capacity and functionality of the cooling system, causing the engine to run hotter and increasing the likelihood of further damage. In addition, cavitation, the formation of cavities in the coolant as it passes through the water pump, causes intense microbursts that will eventually damage the water pump impellers affecting coolant flow. Original Bar's Radiator Leak Stopper is specially designed to seal small leaks and drips in the cooling system, reduce or eliminate cavitation and lubricate cooling system components. Original Bar's Radiator Leak Stopper works on plastic, aluminium and metal leaks, radiators, heater cores, blocks, head gaskets and freeze plugs. In addition, Rhizex particles will break up low pressure cavities caused by cavitation and reduce or eliminate these internal micro explosions. Shake well and pour the entire contents into the radiator (not the overflow reservoir) after the engine cools down. Replace the radiator cap and drive or run the engine for at least 15 minutes. If leaks persist, use a second application. Use one can for 4-cylinder engines and two bottles for 6- and 8-cylinder engines. For best results, use Nural Bar's Radiator Cleaner or Bar's 10 Minute Flush to clean the cooling system of dirty radiators. NOTE: Mechanical attention may be necessary if leaks continue after treatment. Seals leaks throughout the cooling system. Helps keep the cooling system clean. Reduces or eliminates cavitation damage. Lubricates cooling system components. Always use caution when working near an engine or radiator. Use care when removing the radiator cap. DANGER: Opening the cooling system when the engine is hot or running can cause severe burns.
