Brent Radiator Stop Leak stops and seals antifreeze/coolant leaks effectively. It is carefully formulated to address minor to moderate leaks and drips caused by aging, corrosion, and normal cooling system wear. This dispersion compound is designed to protect the cooling system and combustion chamber from coolant loss, increase operational safety, and prevent costly repairs.
Brent Radiator Stop Leak permanently seals hairline cracks in radiators, heater cores, water pumps, and cylinder head gaskets, while also conditioning seals to prevent sweating and seepage. Safe for use in all closed-loop cooling systems, including aluminum and plastic radiators, it does not clog or damage the system.
Directions for Use:
Shake well before use. Add the product to the coolant reservoir or radiator when the engine is cool. Start the engine, open the heating valve, and let it run for 4–8 minutes. After the sealing process is complete, check and top up the coolant level if necessary.
